Paving work is scheduled to begin in August, and final completion is anticipated in late fall of 2022

What to expect:

While paving is underway, motorists will encounter daytime lane restrictions and travel delays. Throughout the project, east- and westbound I-40 may be narrowed to one lane only in each direction. ADOT advises drivers to plan for possible delays while the work is underway.
