Drivers in Flagstaff should plan for lane restrictions on Interstate-40 while construction continues on a West Flagstaff bridge. Both east and westbound I-40 will be reduced to one lane next week between 5 a.m. and 5 p.m. Monday through Friday. Current driving restrictions are ongoing at on and off-ramps at the bridge, as well as the crossroad under the bridge, which will remain closed until November 15th. During next week’s lane reduction, the speed limit will be reduced to 55 miles-per-hour. ADOT reminds drivers to slow down and observe posted speed limits and other construction signs while restrictions are still in place.
