ADOT is starting a much-needed repaving project on Interstate-40. Crews are repaving a ten-mile stretch between Interstate-17 and Walnut Canyon Road in Flagstaff. The work will include replacing the existing pavement in both directions of I-40 and replacing pavement on the on- and off-ramps at four intersections in the project area. Work will also include making repairs to bridge decks along the stretch and repairing guardrail as needed. During construction, portions of the roadway will be reduced to a single lane. Motorists should expect slower traffic and delays. Additionally, motorists can expect some night work with on- and off-ramp closures while the ramps are being paved. The project is expected to last two seasons with an anticipated completion date of fall 2022.
