ADOT project has about 9 miles of new pavement; minor work continues

TUCSON – The Arizona Department of Transportation has completed paving work on a project that’s improved 9 miles of State Route 77/Oracle Road in the Tucson area.

New pavement has replaced worn asphalt throughout the project area between Calle Concordia in Oro Valley and Miracle Mile in Tucson, and on Miracle Mile between Oracle Road and Interstate 10.

The paving is part of a two-and-a-half-year, $34 million project that also included improvements to lighting, sidewalks, drainage, turn lanes and traffic signals on a roadway that carries more than 50,000 vehicles a day.

While motorists should expect to see limited construction activity continue through summer, most remaining work is off the roadway and only expected to involve limited lane restrictions. As it has throughout the project, ADOT will continue maintaining access to all 1,100 businesses in the area.

In addition to pavement, the project included: 

  • Reconstructing and repaving the roadway from River Road to Calle Concordia
  • Adding new dual left turn lanes to the intersection of Magee and Oracle roads
  • Making lighting improvements, including new LED street lights, between River and Ina roads
  • Constructing ADA-compliant ramps, sidewalks, driveways between River and Magee roads to improve pedestrian safety
  • Installing a storm drain system between 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
  • Making roadway drainage improvements
  • Relocating utilities
