What to expect during construction

During construction, lane restrictions may be needed for crews to safely work on the roadway. As a result, drivers should expect slower traffic and delays. Details regarding traffic restrictions will be updated and posted on this project web page prior to the start of work.

ADOT reminds drivers to proceed through the work zone with caution, slow down and watch for construction personnel and equipment. 

Project Schedule

Construction work will begin Sept. 20 and will span over two construction seasons. Construction will shut down for the winter as pavement work cannot be performed during the winter months due to low temperatures and wet weather conditions. 

Schedule subject to change based on weather or other unforeseen circumstances.

Current Restrictions and Closures

ADOT advises drivers to plan ahead for possible delays while the following traffic restrictions will be in place:

  • East- and westbound US 160 will be narrowed to one lane of alternating travel weekdays from 6 a.m. to 6 p.m. beginning Monday, Sept. 20, and continuing through March 2022.
  • Drivers need to be prepared to slow down and stop in the work zone and use caution around construction personnel and equipment while the restrictions are in place.
