Starting the morning of Wednesday, May 26, the westbound Cortaro Road traffic lanes near the interchange will open in a new configuration, as the shared through-left movement under I-10 will be separated. The new lane configuration will allow for improved traffic signal operations.

The paving and striping work is being coordinated with pavement preservation work being completed by the town of Marana.

Drivers should proceed through the work zone with caution, slow down and watch for construction personnel and equipment.
