Due to construction work on Interstate-40 at Fourth Street in Flagstaff, lane restrictions will last through July 3rd. ADOT will narrow westbound I-40 down to one lane under the bridge through June 26th around the clock. Then the eastbound side will be down to one lane from June 26th through July 3rd. During the lane restrictions, east and westbound I-40 traffic will be shifted to one side of the highway using the traffic crossover lanes. The restrictions are needed as work continues on the Fourth Street Bridge.
