From the Arizona Department of Transportation:

Work to add interim improvements at and near the Loop 303 interchange with Grand Avenue (US 60) in Surprise is scheduled to start Monday night, July 29.

Crews will extend a second lane along the northbound Loop 303 off-ramp at Grand Ave, providing additional room for traffic exiting the freeway. The capacity  improvements along the exit ramp will allow for two left-turn lanes to westbound  Grand Ave, a lane allowing turns in either direction and a dedicated right-turn lane for rivers who want to go east on US 60.

The northbound Loop 303 off-ramp at Grand Ave will be closed overnight from 10 p.m. Monday to 4 a.m. Tuesday, July 30, while crews are setting temporary barrier walls for a work zone. Drivers can consider exiting northbound Loop 303 to eastbound Bell Rd and using northbound Reems Rd to reach Grand Ave.

Following Monday night’s closure, Loop 303 drivers should plan for work zone restrictions along the northbound off-ramp to Grand Ave over the next several months.

Other interim improvements to be constructed as part of the $4.6 million project include providing a third eastbound US 60 lane near 163rd Ave. A third left-turn lane will be added for southbound 163rd Ave traffic turning onto eastbound US 60.
The work is scheduled for completion by spring 2025.
