Santa Cruz River Park

Santa Cruz work begins July 15: Loop users may notice soil sampling equipment and support vehicles along the Santa Cruz River section of The Loop from July 15 through early August, weather permitting. The work, which is part of the design of a new dual force main sewer system between Continental Ranch Regional Pump Station and Pima County Wastewater’s Tres Rios plant, is very mobile and will change locations on a day-to-day basis.
The general area where you may intermittently encounter this work is along the west bank of the Santa Cruz River from Ina Road north of Twin Peaks and along the east bank of the Santa Cruz River south of Ina Road. Cones and flaggers may be present at certain times to keep Loopers moving safely through areas adjacent to the sampling operations. Lane restrictions are possible, but no closures are anticipated.

Ajo Way:
The Arizona Department of Transportation will be reconstructing the Ajo Way Bridge over the Santa Cruz River. This bridge removal and replacement project will cause a long-term closure of the Chuck Huckelberry Loop (west bank) underpass at that location beginning October 30, 2018. There is not an existing east bank underpass at this location. ADOT project managers estimate the closure will run through Spring 2020. Crews will use the area to stage equipment and materials for the bridge project. Once complete, the new bridge will re-establish the existing west bank underpass and will also make room for construction of a new underpass on the east bank of the Santa Cruz which will allow the Pima County Regional Flood Control District to extend the shared-use path on the east side between the Julian Wash and Valencia Road.

Other Notices

Please Note: Please remember that Pima County Code (Chapter 6.04.030) requires dogs to be leashed and under control and also requires pet waste to be immediately picked up and properly disposed of in a sanitary manner. This applies to public spaces such as parks, trails, The Loop, open space, nature resource areas, river beds and most every public space except “dog parks”. For more information on responsible pet ownership please visit: Thank you for your anticipated compliance.
