SR 77/Oracle Road: Through late 2023

The Arizona Department of Transportation is paving four miles of State Route 77/Oracle Road with plans to finish by late 2023.

The work will take place on the southern end of the project, with paving operations on Miracle Mile between Interstate 10 and Oracle Road and on Oracle Road from Miracle Mile to River Road.

Most of the work will occur between 7 p.m. and 6 a.m. Sundays through Thursdays.

During work hours, drivers can expect large vehicles and equipment on the roadway, uneven pavement and reduced speed limits. One lane of travel will remain open during pavement operations.

The new pavement is one of many improvements planned as part of a two-year, $34 million project to improve the highway between Interstate 10 and Oracle Road, as well as on Oracle Road from Miracle Mile to Calle Concordia.

Drivers should expect some daytime lane restrictions and delays throughout the project. ADOT will maintain access to the roughly 1,100 businesses in the corridor.
