Interstate 40 in Oklahoma - Route Description

Route Description

Interstate 40 enters Oklahoma near Texola, in Beckham County. It crosses the North Fork of the Red River near Sayre and runs through the south side of Elk City. It then cuts across the northwest corner of Washita County before entering Custer County, where it passes through Clinton and Weatherford. After leaving Weatherford, I-40 then runs across the northern tip of Caddo County before it enters Canadian County.

I-40 runs through the south side of El Reno, entering the Oklahoma City metro. It then passes through Yukon before entering Oklahoma City proper. There, it has a junction with Interstate 44 (the Amarillo Junction). It then runs just south of downtown Oklahoma City on an elevated, dilapidated structure called the I-40 Crosstown, which is scheduled for replacement in 2012. It next meets Interstate 35 in the Fort Smith Junction complex, forming a concurrency with it for about two miles (3 km). It then passes through Del City and Midwest City on a freeway known as the Tinker Diagonal, providing access to Tinker Air Force Base in Oklahoma City.

In far eastern Oklahoma City, I-40 meets Interstate 240 in a partial junction before passing through the north side of Shawnee. In Henryetta, I-40 serves as the northern terminus of the Indian Nation Turnpike. In McIntosh County, it crosses the northernmost arm of Lake Eufaula and meets the US-69 freeway south of Checotah.

Near Webbers Falls, I-40 is the southern terminus of the Muskogee Turnpike. It then crosses the Arkansas River before heading around southern Sallisaw. The interstate crosses into Arkansas north of Moffett.
