After years of construction, the upgrade of Interstate 40 between Midwest City and Oklahoma City is finally finished. The road now has six lanes, new bridges, and redesigned ramps to help reduce traffic near Tinker Air Force Base. Officials held a ribbon-cutting at the I-40 and Douglas Boulevard interchange and named the area after late U.S. senator James Inhofe. With the ceremony complete, the improved highway is now fully open to drivers, as reported KOCO.
Ribbon Cutting And Dedication
The morning ceremony served as both a victory lap for the construction team and a tribute to Inhofe’s legacy. Officials unveiled the interchange’s new name and pointed to the project as a showcase of his influence on transportation spending in the state. "It stands as a testament to Senator in office, long-standing commitment to Oklahoma's infrastructure and to our future growth," officials said, according to KOCO. The station also reported that six bridges along the corridor received major upgrades as part of the work.
Design, Funding And Contractors
The Oklahoma Department of Transportation broke ground on the I‑40/Douglas project in late 2022 and built the interchange as a single‑point urban interchange, a layout intended to move traffic more efficiently while keeping right‑of‑way impacts in check, according to an ODOT news release from that time. In that announcement, ODOT also highlighted a $51 million federal INFRA grant helping to fund the effort and noted that the construction contract went to a team led by Allen Contracting and Shell Construction.
Planning documents from ODOT show the I‑40 improvements stretching a little more than six miles, from Industrial Boulevard to the I‑240 interchange, with the widened lanes and interchange work packaged together as part of the same project.
Cost, Timeline And What Drivers Should Expect
Officials pegged the overall price tag at roughly $170 million and said the I‑40/Douglas overhaul represents the largest‑dollar highway construction contract in the department’s history, according to KOCO. Early coverage around the groundbreaking noted that crews initially targeted a 2025 completion date, a schedule that shifted as workers wrapped up bridge replacements and tied new lanes into the existing roadway, per News9.
For drivers, the on-the-ground changes are straightforward, if long awaited: six continuous lanes through the corridor, rebuilt ramps, and fresh signage guiding traffic through the new single‑point interchange. ODOT officials said the agency will keep an eye on how traffic moves through the area while crews finish remaining punch‑list items.
