All lanes and ramps between Norman and Goldsby are now open following the completion of the I-35/SH-9W interchange reconstruction and I-35 widening project, according to the Oklahoma Department of Transportation (ODOT).

The project included the expansion of I-35 from 4 to 6 lanes from the Canadian River south to the Goldsby interchange, the construction of Oklahoma’s third diverging diamond interchange and the addition of two local street roundabouts.

Motorists are urged to use caution as traffic adjusts to the new interchange layout.

Some additional night closures may be required for minor project wrap up.

The I-35/SH-9W Interchange reconstruction and I-35 widening project was awarded to Sherwood Construction in August 2023 with a low bid of $82 million.

Construction began Jan. 29, 2024 and opened 24 days ahead of schedule, opening the expanded interchange prior to upcoming holiday travel.
