Valencia Intersection

Valencia Road - Kolb Road Intersection Improvement Project

The Regional Transportation Authority managed the design and right-of-way acquisition phases of the Valencia Road, Wilmot Road to Kolb Road, project and these phases are substantially complete. The project has been handed over to the City of Tucson who will administer the construction phase since much of the project is within the City of Tucson as a result of an annexation which occurred in 2013.

The corridor improvement project was approved by Pima County voters in May 2006 as part of the RTA plan. Pima County conducted the initial planning work on the project and turned the project over to the RTA in December 2012 for completion.

The proposed project is known as a PAGI (parkway at grade intersection) and will provide  improvements to alleviate traffic congestion and connect to future improvements to Valencia Road, east to Houghton Road.

The construction phase of the  project is expected to start toward the end of 2017 and at this time is estimated to last approximately 18 months.

A public meeting will be held once a contractor is selected toward the end of 2017. If you would like to be added to a project contact list, please email your contact information to
