UPDATE: Kolb Road: Connection to Sabino Canyon Road

Construction of the extension of Sabino Canyon Road to Kolb Road is in progress, with Tucson-based Ashton Company as contractor for the $12.3 million project.
Project Manager Update
Project manager Joe Chase has moved from Tucson to work in Seattle on their urban streetcar project. Joe worked tirelessly on the Kolb Road: Connection to Sabino Canyon Road project since 2012 to keep it moving successfully ahead and made a special point of working directly with residents and businesses impacted by the new roadway. He has met with residents both in groups and individually to address their concerns and will be missed by many in the community.
We welcome new project manager Austin Wesnitzer, who has been working closely with Joe Chase to become fully knowledgeable on the project to make the transition seamless and bring the project to a successful completion. Austin is a University of Arizona graduate and worked as a structural engineer in the private sector for several years before joining the Tucson Department of Transportation in 2015. If you would like to contact Austin concerning the project, he can be reached at Austin.Wesnitzer@tucsonaz.gov, or 520-837-6614.
Current activities
Work to construct the new intersection connecting Kolb Road with the extension of Sabino Canyon Road began in mid-October 2016, and is scheduled to be complete by mid-December 2016.
Between 6 a.m. and 8 p.m., at least two lanes of travel on Kolb Road will be maintained in each direction. During milling, paving and concrete work, travel on Kolb Road will be reduced to one lane in each direction between 8 p.m. and 6 a.m. Motorists are advised to plan their travel accordingly to account for potential travel delays while driving through the work zone.
Project schedule
The contractor began minor construction in mid-December 2015, and major construction activity began after the first of the year with a project completion date of February 28, 2017. Work is ahead of schedule and is expected to be completed in mid-January 2017. The contractor has made significant progress in the following areas:
  • Noise wall adjacent to the Pantano II neighborhood – 100% Complete

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 as well.

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.
