I-40 bridge improvement project in northeastern Arizona begins May 4

Expect overnight closures with ramp detours on I-40 near New Mexico

PHOENIX – The Arizona Department of Transportation is starting a project to reconstruct the St. Anselm Road bridge over Interstate 40 at milepost 348 between US 191 and the New Mexico state line in the community of Houck.

The bridge, located on the Navajo Nation, will be closed for the duration of the project. Drivers should also expect overnight closures of I-40 during portions of  the project, with traffic using the on- and off-ramps at the St. Anselm Road interchange to exit and re-enter the freeway. 

Westbound I-40 will be closed overnight from 10 p.m. to 5 a.m. beginning Monday, May 18, and continuing through the morning of Friday, May 21. Eastbound I-40 will be closed overnight from 10 p.m. to 5 a.m. beginning Wednesday, May 20, and continuing through the morning of Friday, May 22.

Drivers on St. Anselm Road will need to detour along I-40 to either the Allentown Road exit or the Pine Springs Road exit and make left turns to come back to St. Anselm Road to continue on.

The closures are needed so crews can safely demolish, remove and replace the bridge deck on the St. Anselm Road bridge. 

The project is scheduled to be completed by this fall.
