ORO VALLEY, Ariz. (Feb. 10, 2022) – The Big Wash Trailhead and parking lot will be temporarily closed for bank protection construction starting Feb. 21 through April 4; however, the trail itself will remain open to the public and can be accessed from other locations.

It was the Town’s intent to keep both the trailhead and trail open, as stated in a Sept. 30, 2021 press release announcing construction of the nearby Tranquilo housing development. However, out of an abundance of caution, the decision was made to temporarily close the trailhead for public safety while concrete bank protection is built.

The concrete bank is part of future improvements to this recreational amenity, ensuring protection of the access road, parking lot and trailhead. Bank protection helps safeguard the trailhead and future home development from flooding and erosion. Construction includes extensive earth removal, use of heavy equipment and pouring of concrete. The exposed construction area, work activity, and intensive mobilization of concrete trucks create potential safety issues, so temporary closure is warranted.  Eventually, the trail will be extended, and users can look forward to the construction of a trail along the top of the bank in the fall of 2022, providing a much-needed link to Tangerine Road.

The Big Wash Trailhead is located along Rancho Vistoso Boulevard near Del Webb Boulevard. Trail closure signs will be placed along Rancho Vistoso Boulevard, as well as at the turn-off to the trailhead and at the trailhead itself. Vehicle traffic on Rancho Vistoso Boulevard will not be impacted.
