Drivers should consider detours on City streets and other highways when driving to and from downtown during the Oklahoma Department of Transportation’s construction project on Interstate 235.

The ODOT project is expected to last up to three years on I-235, which connects the Broadway Extension south from Interstate 44 to Interstate 40. Nightly lane closures on I-235 have already started, and traffic restrictions will change throughout the project.

Drivers traveling between downtown and the north Oklahoma City metro can use detours east and west of I-235. The eastern detours are Interstate 35, Martin Luther King Avenue and N Lincoln Boulevard. The western detours are the Lake Hefner Parkway/I-44 and N Classen Boulevard/N Western Avenue.

To get between I-235 and the detour routes, drivers can use NW/NE 36th Street, NW/NE 23rd Street, W/E Reno Avenue and Interstate 40 as east-west routes.

The detour routes are shown on a map posted to
