ADOT improving the bridges along I-40 west of Meteor Crater

Interstate traffic rerouted along on- and off-ramps during construction
July 22, 2019

PHOENIX – Drivers heading along I-40 between Flagstaff and Winslow should slow down and expect delays while work is taking place. The ramp detour will remain in place 24 hours a day, seven days a week. The speed limit is reduced to 45 mph.

In addition to replacing the bridges, crews will also reconstruct the roadway approach to the bridges.

The current detour will last through mid-August while the project is anticipated to wrap up sometime in the fall.

ADOT works to inform the public about planned highway restrictions, but there is a possibility that unscheduled closures or restrictions may occur. Weather can also affect a project schedule. To stay up to date with the latest highway conditions around the state, visit ADOT’s Arizona Traveler Information site at or call 511.
