Kolb Road/Sabino Canyon Update

Construction of the extension of Sabino Canyon Road to Kolb Road is in progress. Tucson-based Ashton Company was selected as contractor for the project with a low bid of approximately $12.3 million.
Project schedule
The contractor began minor construction activities in mid-December to clear the entire length of the project, with major construction activity occurring after the first of the year. To date, the contractor has made significant progress in the following areas:
  • Noise wall adjacent to the Pantano II neighborhood – 90% Complete
  • Roadway grading – 95% Complete
  • Pantano Bridge Drilled Shafts – 30% Complete
  • Pantano Wash Bank Protection – 50% Complete
  • Underground Utilities – 25% Complete
  • Drainage Facilities – 10% Complete
The construction of the noise wall adjacent to the Pantano II neighborhood is expected to be completed by March 21, 2016, with construction of the noise wall adjacent to Udall Park beginning shortly thereafter. As the project progresses, further updates will be forthcoming.
Construction will occur Monday through Friday from 7:30 a.m. to 4 p.m. during the winter months.
Work will take approximately 15 months to complete (weather permitting) with an anticipated completion date of Feb. 28, 2017.

Background information:
Project improvements
Project improvements include two lanes of traffic in each direction, along with new signals at both the Sabino Canyon Road intersections with Kolb Road and Crestline Drive. Improvements also include sound walls where warranted, bridges across Vincent Mullins Landfill and the Pantano Wash, drainage improvements, landscaping, public art, and pedestrian and bicycle facilities along the length of the project. In addition, LED street lighting for driver safety and neighborhood security will be included.
This project is part of the $2.1 billion, 20-year RTA plan that was approved by voters in May 2006.
Lane restrictions
As the majority of the work for this project takes place where no roadway exists, lane restrictions will be minimal. Traffic on Sabino Canyon, south of Tanque Verde, will have at least one through lane in each direction available at all times. Traffic on Kolb Road will have at least two lanes available in each direction at all times.
Access to businesses and local residences
Access to businesses and local residences will be available at all times throughout the course of the project with the exception of temporary delays during grading, demolition work and paving. Residents will be notified two days in advance of any work that will result in a delay that lasts longer than 15 minutes.
We appreciate your patience and want to hear from you if you have any questions, concerns or suggestions.
