Below is a list of traffic projects around southern Arizona. Weather-related road closures in Pima County can be seen HERE.

The list was updated Friday, July 1.

Kolb Road - Sabino Canyon Road to Sunrise Drive: July 5

Crews will switch traffic along Kolb Road from Snyder to Sunrise Drive beginning at 6 a.m. on Tuesday, July 5.

The traffic control will be shifting both northbound and southbound traffic to the center of the new roadway from Snyder Road to Sunrise Drive. This is the same traffic control configuration currently in use from Sabino Canyon Road to Snyder Road.

The newly constructed roundabout at Territory Drive and Kolb Road will also be fully functional at this time. Work will continue on curbs, handrail, landscaping and irrigation work.

Message boards will be in place to direct traffic through the new roundabout. Speed reductions through the project area will continue until work is completed.

Intersection of Los Reales Road/Nogales Highway: July 5-Aug. 5

Crews will begin sewer improvement/rehabilitation work in the vicinity of the intersection of Los Reales Road/Nogales Highway on July 5. Weather permitting, the work is scheduled to continue for one month.

The work will consist of trenching, excavation, sewer line replacement, repaving and striping the disturbed portions of roadway, and final cleanup.

The following lane restrictions will be in place; however, drivers should note that lane restrictions will change as work progresses through the area.

  • Northbound Nogales Highway will be reduced to one lane in the vicinity of the Los Reales Road/Nogales Highway intersection.
  • All turn movements at the intersection will be maintained.
  • No construction-related lane restrictions on southbound Nogales Highway.

The Old Nogales Interceptor Sewer Improvement Project is designed to increase capacity of the existing Old Nogales Interceptor and the Park Avenue Sewer in addition to installing new sewer infrastructure to manage the future anticipated flows along the new Aerospace Corridor and Aerospace Parkway. The total length of the project is nearly 14 miles and extends west along Old Vail Connection Road from the Wilmot State Prison to Nogales Highway and north along the east side of Nogales Highway, where it discharges into the Southeast Interceptor at 36th Street and Euclid Avenue.

Intersection of Moore and Tortolita roads: Through Aug. 5

Crews will perform construction on a traffic circle at the intersection of Moore and Tortolita roads beginning Monday, May 23. The project is scheduled to end Aug. 5.

The work will include curb staking, curb installation, subgrade prep, paving and striping.

Minor delays may occur during this work.

SR 77/Oracle Road: Through late 2022

The Arizona Department of Transportation is paving four miles of State Route 77/Oracle Road with plans to finish by late 2021.

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 through December. 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.

Additional pavement work will resume in 2022.

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.

Speed limit through the project area will remain at 35 mph.

Project Scope

Improvements will include widening of South Houghton Road from a two-lane roadway to a divided four-lane roadway, a separated multi-use path that will connect to the loop and, drainage and intersection improvements. The project is expected to be completed early 2023.
