    Rillito River Park

    A portion of the north bank of the Rillito will be closed between Mountain Avenue and First Avenue June 22-July 17 for installation of artwork around the new bike
    and pedestrian barometer. Users may detour through the Rillito Race Track's parking lot. The path will be open after work hours and on weekends.


    Santa Cruz River Park  

    Simpson Street Bridge: Crews will be performing maintenance on the Simpson Street Bridge that will close a portion of the east side of the Santa Cruz River Park from May 18 to July 10. Users will find detour signs south of 19th Street that will send them west on 19th to S. Kroeger Lane, which turns into W. Simpson St. Note: the bridge deck will be completely removed and replaced with concrete decking (it's currently wood), so there will no way for users to cross the bridge until the project is complete.

    Starr Pass to Congress: Beginning April 29, the west bank pathway on the Santa Cruz River segment of The Loop will be closed weekdays between Starr Pass Boulevard and Congress Street, until the end of June. The closure is necessary due to heavy equipment traveling across the pathway between the Santa Cruz River channel bed and the property located near the base of A Mountain. The pathway will be reopened for weekend use. Please use the east bank Loop pathway during the work week. Closure notices and detour signing will be in place directing you to the east bank pathway.

    Ajo Way:  
    The Arizona Department of Transportation is reconstructing the Ajo Way Bridge over the Santa Cruz River. This bridge removal and replacement project necessitates a long-term closure of the Chuck Huckelberry Loop (west bank) underpass at that location beginning Oct. 30, 2018. There is not an existing east bank underpass at this location. ADOT project managers estimate the closure will run through December 2019. 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.
