Interstate 75 (I-75) runs fromCincinnati toToledo by way ofDayton in the US state ofOhio. The highway enters the staterunning concurrently withI-71 fromKentucky on theBrent Spence Bridge over theOhio River and into theBluegrass region. I-75 continues along theMill Creek Expressway northward to theButler County line just north ofI-275. From there, the freeway runs into theMiami Valley and then passes through theGreat Black Swamp before crossing intoMichigan.

The highway enters the state via theBrent Spence Bridge intoDowntown Cincinnati.I-71 immediately splits off to the east from this point, taking a more easterly route through downtown, while I-75 continues north along the west side of downtown. The Mill Creek Expressway is a heavily trafficked portion of I-75 in Ohio, from the Ohio River at the Kentucky state line to Butler County in Cincinnati's northern suburbs that follows the path of its namesake,Mill Creek, and the former path of theMiami and Erie Canal, and passes through the city's industrial core.

The highway continues north, intersectingI-74 and turning to the northeast. At one point, while passing through the suburb ofArlington Heights, the carriageways split apart and create a wide enough space for the community to be completely enclosed by the Interstate; they rejoin at the other end of the community. The highway then intersects the Cincinnati beltway,I-275, and continues northeasterly through theWest Chester Township,Monroe,Middletown, andFranklin en route to theDayton metropolitan area.

Third crossing, of seven, for I-75 over theGreat Miami River

Once arriving in the Dayton area, I-75 first junctions withI-675, an eastern bypass of Dayton, inMiamisburg. The highway then continues north intoDowntown Dayton, skirting it to the west and junctioning withI-70 near theDayton International Airport.

I-75 at the interchange with the Ohio Turnpike in Rossford

The highway then continues north through the western side of the state towardToledo, passing through the small cities ofTroy,Piqua,Lima,Findlay, andBowling Green. Once the highway arrives in the Toledo metro area, it first intersects withI-475 in the suburb ofPerrysburg. Followed byI-80/I-90 (Ohio Turnpike) in suburb ofRossford and passing throughNorthwood after the interchange. Before skirtingDowntown Toledo to the west, I-75 enters the Toledo city limits and then crosses theMaumee River and continues north into Downtown Toledo. Just north of downtown, in theOld West End I-475 rejoins I-75. After continuing northeasterly, I-75 intersectsI-280, in the North End of the city, which connects the Ohio Turnpike. Following this, I-75 passes through the Point Place/Shoreland lake shore community district. I-75 then entersMichigan and runs parallel with the shore ofLake Erie.

History

[edit]

I-75 in Ohio was built through the 1960s, supplantingU.S. Route 25 (US 25), though much of the freeway was built for US 25. By the time I-75 was finished, US 25ran concurrently with I-75 for all but the northernmost section. By 1974, the US 25 designation was deemed unnecessary and removed from Ohio and Michigan. The northernmost section of US 25 in Ohio becameState Route 25 (SR 25).[3]

In 2005, theOhio Department of Transportation (ODOT) considered reconfiguring I-75's existing interchange in Findlay withUS 224 and SR 15 west as adiverging diamond interchange (DDI) to improve traffic flow. Had it been constructed, it would have been the first such interchange in the US.[4] By 2006, ODOT had reconsidered, instead adding lanes to the existingoverpass.[5][6]

Traffic congestion in the Cincinnati–Dayton corridor has led to proposals for a regional I-75 bypass to divert through traffic.[7]

The segment fromWest Chester toMiddletown was widened in 2010.[8] Construction on the highway continues from Middletown all the way toI-675.

InDayton, ODOT recently completed total reconfiguration of I-75 with several projects occurring simultaneously. The intersection of I-75 and I-70 was reconfigured to handle an increasedtraffic load at the intersection.[9] I-75 through Downtown Dayton at the intersections ofSR 4,US 35, and between were widened and modernized.[10]

ODOT between 2014 and 2016 completed a widening project betweenI-475 in Perrysburg and SR 15 in Findlay to add a third lane in each direction. The SR 15 interchange (which also features the north end ofUS 68) was subsequently rebuilt as well. Several miles north of the southerly I-475 junction, I-75 intersects with I-80/I-90 (Ohio Turnpike).

Work began in May 2019 to convert the existing interchange with Union Centre Boulevard inWest Chester Township, Butler County, to a DDI. The $20-million project was completed in mid-2020.[11][12][13]

Mill Creek Expressway

[edit]

The Mill Creek Expressway generally follows the oldMiami and Erie Canal, which extended from Cincinnati toToledo viaDayton, itself built in theMill Creek valley near Cincinnati. The canal extended from theOhio River along the present locations of Eggleston Avenue andCentral Parkway toMount Storm Park and continued north, remaining close to the Mill Creek Expressway to Butler County.

The first portion of the expressway was built by theWorks Progress Administration (WPA) in 1941[a]—duringWorld War II—to serve theWright Aeronautical plant inLockland. Known then as theWright Highway, it was initially planned to run from Paddock Road (SR 4) inCarthage north toCincinnati-Dayton Road (thenUS 25) nearMaud[17] but was only built—almost completely along the old canal—between Galbraith Road and Glendale-Milford Road (thenSR 126).[citation needed] A short extension was built south to Towne Street inElmwood Place in the late 1940s.[citation needed]

In 1960, plans were announced to add an eastern portion that would result inArlington Heights being surrounded on both sides by the highway.[18]

On January 19, 2015, an overpass north of Hopple Street collapsed onto the highway below at approximately 10:30 pm.[19] The span that failed was the segment of the former northbound ramp to Hopple Street that passed over the southbound lanes of I-75.[20] The overpass had been closed and was in the process of being removed after a replacement ramp was opened on December 26, 2014. The Interstate underneath was open at the time of the failure. One construction worker on the overpass was killed during the collapse by a falling steel beam.[21] A truck driver was injured when theirsemi hit the fallen overpass immediately after the collapse. One other worker was in a backhoe on the bridge but was uninjured.[22]

Future

[edit]

There are plans to convert the existing interchange withSR 725 inMiamisburg to a DDI. The project was to be built in 2023 and its projected cost was $4.1 million, entirely funded by the state.[23] However, in August 2023, ODOT announced that it planned to study the project for a few more years, owing to a traffic signal retiming project completed in March 2022. ODOT suggested that the DDI might actually create more delays along the SR 725 corridor.[24][needs update]

In Cincinnati, approximately 17 miles (27 km) of the highway will be totally reconfigured by three separateODOT projects happening simultaneously. The Brent Spence Bridge Corridor project will replace theBrent Spence Bridge and continue north to theWestern Hills Viaduct. The Mill Creek Expressway project will modernize the Mill Creek Expressway segment of the highway, from the Western Hills Viaduct to theRonald Reagan Cross County Highway interchange. The Thru the Valley project will continue from the Cross County Highway north toI-275. These projects will improve safety by eliminating all left-hand exit ramps and increasing vehicular capacity.

Auxiliary routes

[edit]

I-75 in Ohio has threeauxiliary routes. The southernmost isI-275, which serves as a full loop aroundCincinnati, including segments that extend intoIndiana andKentucky. The northernmost isI-475, a bypass aroundToledo area that also carriesUS 23 for 14 miles (23 km). The third auxiliary route isI-675bypassingDayton to the south and east and connecting toI-70 northeast of the city.

In addition to these auxiliary routes, there are threebusiness routes of I-75. These run along former segments ofUS 25, I-75's predecessor highway. They connect to the downtowns ofTroy andPiqua;Sidney; andFindlay.

Notes

[edit]
  1. ^Only the eastern portion had been completed by December 1941.[14] Construction on the western half was delayed first due to a dispute between local officials and the WPA[15] and later due to the latter's closure.[16]
