TUCSON, AZ — The Arizona Department of Transportation (ADOT) has begun the final phase of a project repaving 10 miles of State Route 77 between Tucson and Oro Valley. Crews recently began replacing about 3 miles of worn pavement between Ina Road and the Rillito River Bridge just south of River Road.

As has been the case with most major work on the $34 million project, the paving will occur overnight to minimize restrictions and delays. Crews will begin with southbound SR 77 at Ina Road and move south and one lane at a time. Once they reach the Rillito River Bridge, work will begin on the northbound lanes. One lane will remain open in each direction at all times.

The project also has improved the safety and traffic flow of SR 77 between Interstate 10 and Miracle Mile, as well as on Oracle Road between Miracle Mile and Calle Concordia. The improvements include:

• Reconstructing and repaving the roadway from River Road to Calle Concordia
• Adding dual left turn lanes to the intersection of Magee and Oracle roads
• Adding LED street lights between River and Ina roads
• Constructing ADA-approved ramps, sidewalks, and driveways between River and Magee roads to improve pedestrian safety
• Installing a storm drain system from River to Orange Grove roads
• Reconstructing driveways, sidewalks, and sidewalk ramps between I-10/Miracle Mile and River Road
• Improving signals and intersections between River and Ina roads
• Improving roadway drainage
• Relocating utilities
