Interstate 40 (I-40) is anInterstate Highway inOklahoma that runs 331 miles (533 km) across the state fromTexas toArkansas. West ofOklahoma City, it parallels and replaces oldU.S. Highway 66 (US-66), and, east of Oklahoma City, it parallelsUS-62,US-266, andUS-64. I-40 is the longest Interstate highway in Oklahoma.

Cities along the route includeErick,Sayre,Elk City,Clinton,Weatherford, Oklahoma City and its suburbs (El Reno,Yukon,Del City, andMidwest City),Shawnee,Okemah,Henryetta,Checotah, andSallisaw.

I-40 enters Oklahoma nearTexola inBeckham County. It crosses theNorth Fork of the Red River nearSayre and runs through southernElk City. It then cuts across northwestWashita County before enteringCuster County. There, it passes throughClinton andWeatherford. After leaving Weatherford, I-40 then runs across northernCaddo County. After that, it enters theOklahoma City metropolitan area atCanadian County.

I-40 runs through the southside ofEl Reno as it enters the Oklahoma City metropolitan area. It then passes throughYukon before entering Oklahoma City city limits. In west Oklahoma City, I-40 has a junction withI-44. It then runs just south of downtown Oklahoma City on a new 10-lane section.^[2] I-40 then interlines withI-35 at theDallas Junction complex. This forms aconcurrency with it for two miles (3.2 km). After the Dallas Junction, I-40 then passes throughDel City andMidwest City on the Tinker Diagonal. This provides access toTinker Air Force Base in east Oklahoma City.

In far eastern Oklahoma City, I-40 meetsI-240 in a partial junction. Afterward, it passes through the northside ofShawnee. This marks the eastern end of the Oklahoma City metropolitan area. InHenryetta, I-40 serves as the northern terminus of theIndian Nation Turnpike. InMcIntosh County, it crosses the northernmost arm ofLake Eufaula. Afterward, it meetsUS-69 south ofChecotah.

NearWebbers Falls, I-40 is the southern terminus of theMuskogee Turnpike. It then crosses the Arkansas River before passing through southernSallisaw. The Interstate crosses into Arkansas north ofMoffett.

West of Oklahoma City, I-40 parallels and replaces Old US-66. US-66 was decommissioned in Oklahoma in 1985.

The I-40 bridge over theMcClellan–Kerr Arkansas River Navigation System nearWebbers Falls was struck by a barge on May 26, 2002, causing thebridge to collapse and resulting in the death of 14 people.

Westbound I-40 traffic was detoured throughGore and Webbers Falls alongSH-10,US-64, andSH-100, while eastbound traffic was diverted throughPorum andStigler alongSH-2,SH-9, andUS-59.^[3] Delays of 30 to 50 minutes on the 12-mile (19 km) westbound detour were typical, although trains passing through Gore could lengthen wait times by 15 minutes. The eastbound detour added 40 miles (64 km) and two hours to the typical trip. Some travelers chose to avoid the area entirely; oneTulsa trucking firm detoured trucks viaSpringdale, adding 70 miles (110 km) to the trip.^[4][5]

The detour significantly impacted the town of Gore. Local firefighters directed traffic there 24 hours a day, with daytime temperatures approaching 100 °F (38 °C). Businesses in Gore reported loss of revenue due to the traffic; onegas station reported a 30% decline in revenue while traffic was detoured through town.^[5]

On the evening of May 31, 2013, a very large and powerfulmultiple-vortex tornado occurred over rural areas of central Oklahoma, passing aroundEl Reno, Oklahoma. This is known to be the largest tornado ever recorded at 2.6 miles (4.2 km) wide and was responsible for eight fatalities and 151 injuries. Four of those fatalities were storm chasers, the first known deaths in storm chasing history.^[6] This tornado crossed over I-40 at around 6:33 pm CDT after hitting peak strength and maximum width and did a 270-degree counterclockwise loop north of the Interstate, clippingSH-66 before traveling on and along the Interstate, approachingOklahoma City at a very slow speed. The tornado dissipated at 6:43 pm near exit 130 (Banner Road).^[7]

On December 17, 2015, a Pasadena, Texas, man allegedly shot and killed two people on I-40 near Weatherford, Oklahoma. He was arrested by police in Clinton, Oklahoma.^[8]

The original I-40Oklahoma City Crosstown Expressway was built in 1966 mostly as an elevated route;^{[citation needed]} however, this former stretch was too narrow for existing traffic and was frequently in disrepair. In response, the I-40 Crosstown Expressway has been relocated a few blocks south of the original route and the original bridge torn down. The project was completed in February 2012.^[2]

The new I-40 Crosstown Expressway has been designed to carry more than 170,000 vehicles per day traveling at 60 mph (97 km/h) using at least 10 lanes for traffic and has breakdown lanes for disabled vehicles and future lane expansion.

When the new crosstown opened in 2012, nearly 95% of non–rush hour traffic was considered 'through traffic' (i.e., not transferring to or from downtown streets).^{[citation needed]}

A landscaped boulevard (Oklahoma City Boulevard) was completed in 2019, replacing the original I-40 Crosstown Bridge right-of-way throughdowntown Oklahoma City, similar to theI-30 reconstruction through downtownFort Worth, Texas.

I-40 has eightbusiness routes in Oklahoma, six of which are old alignments ofUS-66. A number of other old alignments of US-66 are also present west of Oklahoma City.

• Interstate 40 Business (I-40 Bus., formerly US-66) inErick is abusiness loop that runs from I-40 two miles (3.2 km) west of Erick to the old alignment of US-66, through Erick, and back to I-40 four miles (6.4 km) east of Erick.
• I-40 Bus. (formerly US-66) inSayre is a business loop that begins two miles (3.2 km) south of Sayre atUS-283, runs north into the city, and then leaves Sayre to the east, rejoining I-40 two miles (3.2 km) east of US-283.
• I-40 Bus. (formerly US-66) inElk City is a business loop that begins at exit 32 seven miles (11 km) west of Elk City. It runs for 10 miles (16 km) through Elk City, rejoining I-40 at exit 41.
• I-40 Bus. (formerly US-66) inClinton is a business loop that begins at exit 65, runs five miles (8.0 km) through Clinton, and rejoins I-40 at exit 69.
• I-40 Bus. (formerly US-66) inWeatherford is a business loop that exits I-40 at exit 82B, runs four miles (6.4 km) through Weatherford, and rejoins I-40 at exit 82.
• I-40 Bus. (formerly US-66) inEl Reno is a business loop that exits I-40 at exit 119, runs eight miles (13 km) through El Reno, and rejoins I-40 at exit 125, the interchange withUS-81.
• I-40 Bus. (formerlyUS-62/US-75) inHenryetta is a business loop that leaves I-40 at exit 237, runs four miles (6.4 km) through Henryetta, and rejoins I-40 at exit 240, the interchange with US-75 and the Indian Nation Turnpike.
• I-40 Bus. inSallisaw is a business loop that leaves I-40 at exit 308 (US-59) runs four miles (6.4 km) through Sallisaw, and rejoins I-40 at exit 311,US-64.
