Motorists planning travel in and around Flagstaff should plan for I-40 restrictions Drivers in northern Arizona should prepare for traffic shifts and lane restrictions on Interstate 40 at Exit 191 in west Flagstaff as crews continue project work to replace a bridge, according to the Arizona Department of Transportation.

This location is approximately three miles west of the I-40 interchange with Interstate 17.

Eastbound I-40 will be reduced to one lane and traffic shifted to the north side of the roadway beginning at 6 p.m. Friday, July 23. A similar shift will occur on Friday, July 29 for the westbound lanes. In addition, there will be a 15-foot vehicle width limit in place and the speed limit will be reduced to 55 mph. These restrictions will be in place through mid-fall this year.

Ongoing restrictions at this location include the closure of the on- and off-ramps as well as the crossroad under the bridge.

The project is scheduled to be completed in fall 2022.
