What to expect during construction

During construction, lane restrictions will be in place for crews to safely work on the roadway. As a result, drivers should expect slower traffic and delays.

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

The project is complete.
