ADOT crews will be busy working on Interstate-40 in Flagstaff this week. There will be overnight lane restrictions on eastbound I-40 from the I-17 interchange to Country Club Drive from Tuesday through Friday so crews can work on pavement preservation. Work will take place in the overnight hours from 8 p.m. until 5 a.m. Eastbound I-40 will be narrowed to one lane in work areas. Law enforcement may be on site to help with traffic control and there will be a 16-foot vehicle limit restriction in place. ADOT warns drivers to slow down and use caution around workers and equipment while pavement repairs are underway.
