Interstate 94 (I-94) is a part of theInterstate Highway System that runs fromBillings, Montana, to theLower Peninsula of the US state ofMichigan. In Michigan, it is astate trunkline highway that enters the state south ofNew Buffalo and runs eastward through several metropolitan areas in the southern section of the state. The highway servesBenton Harbor–St. Joseph nearLake Michigan before turning inland towardKalamazoo andBattle Creek on the west side of the peninsula. Heading farther east, I-94 passes through rural areas in the middle of the southern Lower Peninsula, crossingI-69 in the process. I-94 then runs throughJackson,Ann Arbor, and portions ofMetro Detroit, connecting Michigan's largest city to itsmain airport. Past the east side ofDetroit, the Interstate angles northeasterly through farmlands inThe Thumb toPort Huron, where the designation terminates on theBlue Water Bridge at theCanada–United States border.
The first segment of what later became I-94 within the state, the Willow Run Expressway, was built nearYpsilanti andBelleville in 1941, with an easterly extension to Detroit in 1945. This expressway was initially numberedM-112. In the mid-1950s, state and federal officials planned an Interstate to replace the original route ofUS Highway 12 (US 12). By 1960, the length of I-94 was completed from Detroit to New Buffalo. Two years later, the US 12 designation was dropped from the freeway. Subsequent extensions in the 1960s completed most of the rest of the route, including the remaining sections between Detroit and Port Huron which superseded the routing ofUS 25. The last segment opened to the public in 1972 when Indiana completed its connection across the state line. Since completion, I-94 has remained relatively unchanged; a few interchanges have been rebuilt, a second span was constructed for the Blue Water Bridge, and, in 1987,a plane crashed on the freeway during takeoff from the airport in Detroit. The routing of I-94 is notable for containing thefirst full freeway-to-freeway interchange in the United States, connecting to the Lodge Freeway (M-10), and for comprising the first complete border-to-border toll-free freeway in a state in the United States. The highway has one auxiliary route,I-194, which serves downtown Battle Creek, and eightbusiness routes. Various segments have been dedicated to multiple people and places.
The entire length of I-94 is listed on theNational Highway System,[3] a network of roadways important to the country's economy, defense, and mobility.[4] The freeway carried 168,200 vehicleson average betweenI-75 and Chene Street inDetroit, which is the peak traffic count in 2015, and it carried 12,554 vehicles immediately west of theBlue Water Bridge inPort Huron, the lowest traffic count in 2015.[5] As the state trunkline highway closest to the lake shore in these areas, I-94 carries theLake Michigan Circle Tour south ofBenton Harbor–St. Joseph and theLake Huron Circle Tour in the Port Huron area.[6] Sections through the Detroit area are named the Detroit Industrial and Edsel Ford freeways. I-94 in the state is either a four- or six-lane freeway for most of its length; one segment in the Detroit area has up to 10 lanes total near the airport.[7]
I-94 enters Michigan from Indiana south of New Buffalo. The freeway runs northeasterly through ruralMichiana farmland in the southwestern corner of the Lower Peninsula and parallels the Lake Michigan shoreline about three miles (4.8 km) inland. I-94 traverses an area just east of theWarren Dunes State Park as the freeway runs parallel to the Red Arrow Highway,[6][7] a former routing ofUS 12 named after the32nd Infantry Division (Red Arrow Division).[8] The freeway crosses its companion highway south of St. Joseph; Red Arrow turns northward carrying the business loop for Benton Harbor and St. Joseph (Business Loop I-94, [BL I-94]). The Interstate curves further inland to bridge theSt. Joseph River near Riverview Park.[6][7] East of Benton Harbor, I-94 meets the other end of BL I-94 at an interchange whereUS 31 merges onto the freeway.[9] East of theSouthwest Michigan Regional Airport, I-94/US 31 meets the southern end ofI-196; US 31 departs the I-94 freeway to follow I-196, and I-94 continues its course away from Lake Michigan.[6][7]
South ofColoma, the trunkline turns eastward and roughly follows thePaw Paw River on a course that takes it south ofWatervliet andHartford. Between the latter two cities, the freeway transitions from northeasternBerrien County into westernVan Buren County. It curves around and between Lake Cora and Threemile Lake near the junction with the northern end ofM-51. About four miles (6.4 km) further east, I-94 crossesM-40 south ofPaw Paw. Continuing eastward, the Interstate runs throughMattawan before entering westernKalamazoo County.[6][7]
InTexas Township, the freeway enters the western edges of the Kalamazoo suburbs. South of the campus forWestern Michigan University's College of Engineering & Applied Sciences inPortage, I-94 intersectsUS 131. Near theKalamazoo/Battle Creek International Airport, the Interstate passes into the southeastern corner of Kalamazoo before enteringComstock Township. The freeway intersects the eastern end ofBusiness Spur I-94 (BS I-94) at a partial interchange near Morrow Lake in the township. I-94 continues out of the eastern Kalamazoo suburbs, paralleling theKalamazoo River through theGalesburg area.[6][7] Before crossing intoCalhoun County on the west side ofBattle Creek,[1] I-94 has the only driveway on any of Michigan's Interstate Highways for a gate providing access for military vehicles into theFort Custer Training Center.[10]
The Interstate enters Calhoun County southwest of theW. K. Kellogg Airport and enters the city of Battle Creek. Immediately east of the county line, the freeway has an interchange with the western end ofBattle Creek's business loop. Next toLakeview Square Mall, I-94 meets its only auxiliary Interstate in Michigan:I-194. I-94 turns to the northwest to roundBeadle Lake, intersectingM-294 before spanning the Kalamazoo River. East of the river crossing, the freeway meets an interchange forM-96,M-311, and the eastern end of the Battle Creek business loop nearFireKeepers Casino Hotel inEmmett Township. Turning back eastward, the Interstate exits the eastern Battle Creek suburbs and continues to an interchange withI-69 nearMarshall; thebusiness loop for Marshall follows I-69 southward.[6][7]
Continuing eastward, I-94 traverses rural land on the north side of Marshall. The freeway runs north of, and parallel to, the Kalamazoo River through eastern Calhoun County. It angles southeasterly towardAlbion before returning to an easterly course on the north side of town. I-94 crosses into westernJackson County before intersectingM-99. From there, it runs generally due east with a jog aroundParma. West of thecounty airport, theJackson business loop followsM-60 southward, and I-94 travels through the north side ofJackson. North of downtown,US 127 merges in from the north andruns concurrently with I-94 around the city. Southeast ofMichigan State Prison, US 127 departs to the south, and I-94 continues eastward through the rest of the county.[6][7]
The freeway runs north of the ChryslerChelsea Proving Grounds inChelsea next to theM-52 interchange. As I-94 continues easterly, it passes into the western edge of theAnn Arbor area. West of downtown, theM-14 freeway splits off to the northeast, and the Interstate turns to the south and southeast to curve around the south side of the city. The freeway passes betweenBriarwood Mall andAnn Arbor Municipal Airport. On the southeastern corner of Ann Arbor, I-94 intersectsUS 23 and continues around the south side ofYpsilanti. South of that city, the freeway also carries US 12 and crosses theHuron River north of the river's mouth atFord Lake. I-94 jogs southeasterly around the south side ofWillow Run Airport complex, separating from US 12 and enteringWayne County.[6][7]

South of Willow Run, the Interstate parallels the north shore ofBelleville Lake. East of the water body, it intersectsI-275 near the northwest corner ofDetroit Metropolitan Airport and angles northeasterly through the southwestern Detroit suburbs along the Detroit Industrial Freeway. I-94 uses theGateway Bridge over thesingle-point urban interchange (SPUI) atUS 24 (Telegraph Road) inTaylor;[6][7] these bridges were inspired bySuper Bowl XL and provide a western entrance to the city.[11] Further east, the Interstate intersectsM-39 (Southfield Freeway) and passes theUniroyal Giant Tire inAllen Park. I-94 then turns to the northeast through theFord River Rouge complex inDearborn before turning back easterly on the Edsel Ford Freeway into Detroit.[6][7]
I-94 traverses Detroit in an east–west direction well inland of, and parallel to, theDetroit River. The freeway intersectsI-96 (Jeffries Freeway) andM-10 (Lodge Freeway) on the West Side, passing the main campus ofWayne State University before entering the East Side atM-1 (Woodward Avenue). Immediately east of the interchange withI-75 (Chrysler Freeway), I-94 forms the southern border of theMilwaukee Junction district. The Edsel Ford Freeway continues through residential neighborhoods of Detroit's East Side. The Interstate turns more northerly, mimicking the shoreline ofLake St. Clair, and exits Detroit forHarper Woods. Just north of the interchange forM-102 (Vernier Road), the freeway crosses 8 Mile Road and entersMacomb County.[6][7]
Running northward through Macomb County, I-94 meets the eastern end ofI-696 (Reuther Freeway) about three miles (4.8 km) north of the county line inSt. Clair Shores. The freeway continues to parallel the lakeshore and travels to the west ofSelfridge Air National Guard Base inHarrison Township. It turns back to the northeast at 23 Mile Road at the interchange withM-3 andM-29. North of 26 Mile Road, the freeway exits the northern suburbs and passes into farmland inThe Thumb region.[6][7]
South of Michigan Meadows Golf Course, I-94 crosses County Line Road and entersSt. Clair County. The freeway continues northeasterly as far asMarysville before turning northward nearSt. Clair County International Airport. From there, it runs roughly parallel to theSt. Clair River. The Interstate travels along the western edge of residential areas for Marysville and Port Huron as it continues northward. Immediately west of downtown Port Huron, it intersects I-69; the two freeways merge and turn first east and then north through an interchange that also features connections toBL I-69.[6][7]
I-94/I-69 turns back to the east about a mile (1.6 km) north of their confluence to span theBlack River north of downtown. On the eastern bank of the river, there is one final interchange forM-25 and BL I-69/BL I-94 before the freeway reaches the toll and customs plazas for the twin-span Blue Water Bridge. Past these plazas, I-94/I-69 ascends the approach to the bridge which crosses the St. Clair River toPoint Edward (Sarnia), Ontario. At the international boundary at the center of the river, the Interstate designations jointly terminate, becomingOntario Highway 402.[6][7]
The first major overland transportation corridors in the future state of Michigan were theIndian foot trails.[12] One of these, the St. Joseph Trail, followed the general route of the modern I-94 across the state from theBenton Harbor–St. Joseph area east to theAnn Arbor area.[13] TheState Trunkline Highway System was created on May 13, 1913, by an act of theMichigan Legislature; at the time, Division 6 corresponded to the rough path of today's I-94.[14] In 1919, theMichigan State Highway Department (MSHD)[a] signposted the highway system for the first time,[17] and three different highways followed sections of the modern I-94 corridor. The originalM-11 ran from the Indiana state line north toColoma whereM-17 connected easterly toDetroit. The third highway wasM-19 from Detroit northeast toPort Huron.[18]
On November 11, 1926, theUnited States Numbered Highway System was approved by theAmerican Association of State Highway Officials (AASHO),[19][b] and the original route ofUS 12[c] replaced the highways from the state line northeasterly to Detroit;US 31 overlapped the highway between St. Joseph andWatervliet. The remainder of the future I-94 corridor was served byUS 25 between Detroit and Port Huron.[21] The first span of theBlue Water Bridge opened between Port Huron andPoint Edward, Ontario, in 1938.[22]

The first segments of upgraded highways along the future route of I-94 were added duringWorld War II. Construction on the Willow Run Expressway started in 1941 before the US entered the war. It was opened on September 12, 1942, to provide improved access toFord Motor Company'sWillow Run bomber plants.[23] The highway was given the M-112 designation at the time.[26] Theexpressway was extended eastward as the Detroit Industrial Expressway into Detroit; the first section opened in 1943 and the remainder was completed in March 1945.[23] Land acquisition for the Edsel Ford Freeway started in 1945. Originally referred to as the Crosstown Freeway, the freeway became known as the Edsel Ford Freeway following an April 1946 petition.[27] Theinterchange between the Lodge Freeway and the Edsel Ford Freeway was built in 1953 as the first full freeway-to-freeway interchange in the US.[28][29] In mid-1956, the M-112 designation was decommissioned and replaced by a rerouted US 12.[24][25] During the mid-1950s, theDetroit Streets and Rails campaign proposed a high-speed rail line in the median of the Willow Run, Detroit Industrial and Edsel Ford freeways; instead of building the rail line, special boarding stations adjacent to dedicated bus lanes in the interchanges along the highway were used.[30]
In other parts of the state, other segments of highway were built to bypass the cities along the future I-94 corridor. In 1940, a southern bypass of Battle Creek opened along Columbia Avenue, and the former routing through downtown on Michigan Avenue became Business US 12 (Bus. US 12).[31][32] In late 1951 or early 1952, a northerly bypass of Jackson opened, and the former route through downtown on Michigan Avenue became another Bus. US 12.[33][34] By the next year, the western half of the Jackson bypass opened, including a bypass ofParma.[35][36] In 1954, a new bypass of Kalamazoo and Galesburg opened; US 12 was rerouted to follow the new highway whileM-96 replaced part of the old route and US 12A in the area.[37][38]
The first planning maps from 1947 for what later became theInterstate Highway System included a highway along I-94's route in Michigan.[39] This highway was included on the 1955 plan for the "National System of Interstate and Defense Highways" with a proposed spur in the Battle Creek area.[40] The modern I-94 was numbered I-92 between Benton Harbor–St. Joseph and Detroit with I-77 from Detroit to Port Huron in the August 1957 plans.[41]

In April 1958, the MSHD wanted to provide a single number for a more direct routing of a Detroit–Chicago freeway; the state proposed rerouting I-94 to replace I-92 in the state, but retained the I-77 designation.[42] On June 27, 1958, AASHO adopted their original numbering plan for Michigan, minus the state's proposed changes.[43] Around the same time, a section ofM-146 near Port Huron was converted into an approach freeway for the Blue Water Bridge.[44][45]
In January 1959, officials announced that sections of US 12, the Willow Run, Detroit Industrial and Edsel Ford expressways were to be given the I-94 designation, temporarily co-designated with US 12. These sections connected Ann Arbor to Detroit, along with a bypass of Kalamazoo to Galesburg and a bypass of Jackson.[46] Later that year, additional segments of I-94 were opened, starting with a 10-mile (16 km) section from Hartford to Coloma, then another from Paw Paw to Kalamazoo which connected with a segment between Galesburg to Battle Creek. The overall 45-mile (72 km) section from Paw Paw to Battle Creek was dedicated on December 7, 1959.[47] In addition, a new northwest–southeast section of freeway was built east of Ypsilanti to create a more gradual curve in the routing between present-day exits 185 and 186,[48] the original routing of the Willow Run Expressway having followed present-day Wiard Road.[49] Signage for the state's Interstate Highways was placed on hold pending finalization of the numbering scheme,[50] and by late 1959 that signage was being added starting with I-75[51] and followed by the other open segments of freeway in the state.[2]
Sections of freeway opened in southwestern Michigan in 1960 between the Benton Harbor–St Joseph area and between Jackson and Ann Arbor; the latter was built over existing portions of US 12.[45] In this year, Michigan became the first state to complete a border-to-border toll-free Interstate within their state, running for 205 miles (330 km) from Detroit toward New Buffalo,[52] creating the longest toll-free freeway in the country at the time.[53]
In January 1962, the US 12 designation was removed from the I-94 freeway. In the process, the designation was transferred to replace the US 112 designation in its entirety.[54] After this transfer, I-94 was no longer concurrent with US 12, except for the Ypsilanti bypass.[55] In 1963, the freeway was extended south of New Buffalo to end atM-239. Traffic was diverted down M-239 into Indiana whereState Road 39 carried traffic the rest of the way to theIndiana Toll Road.[56] By the end of the year, a section of highway opened between Mount Clemens and Marysville, andUS 25 was rerouted to run concurrently along the freeway from the New Baltimore area northward.[57][58]
The eastern terminus of I-94 in the Port Huron area was dedicated on October 14, 1964, signaling the completion of the highway between Marysville and the Blue Water Bridge.[60] This completion displaced part of the M-146 bypass of Port Huron, the southern leg of which was retained as a connector to present-day Lapeer Road.[61] Two years later, the gap between the Wayne–Macomb county line and the end of the freeway near Mount Clemens was filled in when another section of freeway opened.[62][63] In late 1964, a plan was approved to improve the interchange with Telegraph Road (US 24), as the original interchange did not feature access in all directions.[64] North ofAlbion, the route of the freeway previously crossed a branch of theNew York Central Railroad at-grade; the crossing was eliminated when the tracks were removed in 1968.[65]
The sections originally designated as the Willow Run Expressway were rebuilt from Rawsonville Road inBelleville to Ozga Road inRomulus starting in 1972. As part of this reconstruction, the segment between Haggerty and Ozga roads was widened from four to six lanes, and the eastbound lanes were realigned to facilitate construction of an interchange withI-275, a western bypass of Detroit which was under construction at the time. The Willow Run segment was also resurfaced at this point, as the old road bed did not contain steel mesh.[23] Construction of this interchange also obliterated a partial interchange with Huron River Drive.[66][67]
The final section of I-94 in Michigan opened to traffic on November 2, 1972, when the connection across the state line into Indiana was dedicated. This last segment in Michigan between M-239 and the state line opened when Indiana completed an 18-mile (29 km) segment of freeway in their state.[68]
The interchange with the Southfield Freeway (M-39) was closed entirely in 1985 to replace the original exit design, which included four on-ramps that sharply merged into the left lanes of I-94.[69] Reconstruction added new on-ramps that merge into the freeway's right lane, while also moving the carriageways of I-94 closer together.[70]
On August 16, 1987,Northwest Airlines Flight 255 crashed after attempting to take off fromDetroit Metropolitan Airport, killing all but one passenger upon exploding at the I-94 overpass over Middlebelt Road;[71] that overpass was not damaged in the crash.[72] The freeway was closed until August 18,[73] and a memorial was later installed near the interchange between I-94 and Middlebelt Road.[74]
The completion of I-69 in the 1980s, and the approval of theNorth American Free Trade Agreement, increased traffic at the Blue Water Bridge. A new toll and customs plaza was built in 1991,[75] and, later the next year, an international task force determined that traffic on the existing structure was exceeding capacity. Environmental planning started in 1993, and construction started on the second span between Port Huron and Point Edward, Ontario in 1995.[76] In July 1997, the second span opened.[77] The original span was closed for rehabilitation, and both were opened to traffic in 1999.[76]
The interchange with US 24 (Telegraph Road) following its mid-1960s redesign had only two bridges, and left-hand exits were used throughout.[78] This interchange was reconfigured in 2005 to aSPUI design that was completed in December of that year.[79] A pair of bridges called theGateway Arch Bridges (alternately "Gateway to Detroit"[80]) was incorporated in the new interchange.[81]
In 2011, construction was started to widen I-94/I-69 approaching the Blue Water Bridge and to allow for dedicated local traffic and bridge traffic lanes.[82] The lane configuration changes confused drivers in the area, especially motorists with outdatedGPS devices;[83] because of this, MDOT installed updated signs complete with American and Canadian flags to help prevent drivers from heading to Canada by mistake.[84]
Additional construction in the Port Huron area started in late 2013 to rebuild and reconfigure the I-94/I-69 interchange outside the city. The project improved 3.7 miles (6.0 km) of freeway, replaced several bridges and ramps and cost $76 million (equivalent to $101 million in 2024[85]). In June 2014, MDOT closed the ramps from I-69 eastbound to BL I-69 through the interchange until later in the year.[86] The project was completed in September 2015.[87]
In 2016, the sections of I-94 from the Indiana state line to theM-63 interchange was designated as part of theWest Michigan Pike Pure Michigan Byway.[88] The West Michigan Pike originated in efforts in the 1910s to improve a highway along the western part of the Lower Peninsula of Michigan and to increase tourism along the Lake Michigan shore. Theauto trail was eventually superseded by US 12 and US 31 after the creation of theUnited States Numbered Highway System in 1926.[89]
In 2020, work began on the final link of theSt. Joseph Valley Parkway to connect the US 31 freeway to I-94 east of Benton Harbor. The project cost $121.5 million and involved reconstructing the interchange with the eastern terminus of BL I-94 and 3.5 miles (5.6 km) of I-94 in the area. US 31 was rerouted to follow its new freeway section for 1.8 miles (2.9 km) from the previous end of the freeway at Napier Avenue that opened in 2003 to I-94 at BL I-94, where US 31 then followed I-94 to the I-196 interchange as before.[90] This new routing opened on November 9, 2022.[9]
In December 2022, theMichigan Department of Transportation (MDOT) procured a statewide tolling study. Under the study, I-94 would be the first highway to be converted into a toll road starting in 2028.[91] Lawmakers have not yet acted upon the department's recommendation in the proposal.[92]
Construction began on August 7, 2023, on a privately funded three-mile (4.8 km) MDOT pilot project to upgrade the left lane forconnected andautonomous vehicles between Ann Arbor and Detroit.[93]
As the originalexpressway through the center of Detroit was being planned in the 1940s, it was unofficially named the Harper–McGraw Expressway after the streets along which it was to run. There was some initial support to name it afterRoy D. Chapin, the late president of theHudson Motor Car Company and a former US secretary of commerce under PresidentHerbert Hoover. On April 23, 1946, theDetroit Common Council voted instead to name the highway afterEdsel Ford, the son ofHenry Ford and president of theFord Motor Company from 1918 until his death in 1943.[94]
Two other original sections of I-94's predecessor highways in the Detroit area were given early names. The westernmost of these is the Willow Run Expressway, named for theWillow Run complex. The plants at Willow Run producedB-24 Liberator bombers for Ford Motor Company during World War II.[95] The second, the Detroit Industrial Expressway, continued the route of the Willow Run Expressway eastward into Detroit. Both highways were built to move workers from Detroit to the industrial plants at Willow Run during the war and were later incorporated into I-94 in the 1950s as part of a Detroit–Chicago highway.[96]
The section of I-94 northeast of Detroit was named after former CongressmanJames G. O'Hara by theMichigan Legislature. O'Hara was a World War II veteran who served in theUS House of Representatives from 1959 until 1977. During his tenure in Congress, he procured federal funds for the construction of I-94 through his district. The first attempt to name the highway after him failed in 1991, but the honor was included in a budget bill passed in 1997. The section of I-94 was dedicated on October 16, 1998, after donors privately raised nearly $10,000 (equivalent to $18,000 in 2024[85]) to pay for the highway signs.[97]
A segment of I-94 inBattle Creek between the exits forBL I-94 andI-194 was named the 94th Combat Infantry Division Memorial Highway by the Michigan Legislature in 2002. The name honors the US Army's94th Infantry Division, which was activated at nearbyFort Custer in 1942 and served with distinction in the European theater of World War II. Because the unit originated in Battle Creek, and its number matched that of the freeway, the Legislature added the designation by passing Public Act 305 of 2002. The name was dedicated in ceremonies at a rest stop along the section of I-94 on September 28, 2002.[98]
Another piece of I-94 in Calhoun County was designated in 2004 as part of the Underground Railroad Memorial Highway.[d] Starting in 1990, theNational Park Service started working to identify routes of theUnderground Railroad. The Battle Creek area was active in the railroad during the Civil War, and the section of I-94 between exits 98 and 110 east of Battle Creek was included in the memorial designation.[99]
In June 2012, after a resolution passed by the Michigan Legislature was signed by GovernorRick Snyder, a portion of I-94 inTaylor between Inkster and Pelham roads was named the Auxiliary Lt. Dan Kromer Memorial Highway after a 20-year veteran of the Taylor Police Department, who was killed in 2010 while helping motorists who had car trouble.[100]

The other eight highways arebusiness loops of I-94 that connect various cities' downtowns with the main freeway. Unlike I-194, these loops are not freeways.
