ORO VALLEY, Ariz. (Sept. 30, 2021) - Big Wash Trailhead users will start seeing construction equipment and activity as crews begin to clear vegetation adjacent to the trailhead for future bank protection. But rest assured, the trail and parking lot will remain open, with no detours or closures.

The Big Wash Trailhead is located along East Rancho Vistoso Boulevard at North Del Webb Boulevard, and the clearing, immediately to the south and west of the trailhead, is associated with the new Tranquilo at Rancho Vistoso subdivision. The subdivision, which is in the early stages of grading, will eventually have 227 homes.

Throughout the project, the trailhead parking lot will remain open, and trail users should continue to access the trailhead using the current entrance on East Rancho Vistoso Boulevard.

The Tranquilo development will include future improvements to the trailhead. New bank protection will protect the trailhead from future flooding and erosion. Eventually, once bank protection is finished, the Big Wash Trail will be extended south to Tangerine Road.

There is no set date as to when construction will be finished. On-site signage will indicate any changes that may impact trail users. The Town of Oro Valley’s intent is to keep the trailhead and trail open for the duration of this project by coordinating with Pima County and the developer. In the meantime, users should be mindful of traffic control, signage and construction equipment. Be safe and have fun, Oro Valley!
