    Julian Wash

    Augie Acuna Los Ninos Park: The Augie Acuña/Los Niños Park parking lot will be closed to the public March 16-21 for refurbishment. It's scheduled to re-open March 22.

    Rillito River Park

    Camino de La Tierra: Loop users can expect temporary closures on the north and south banks of the Rillito west of Camino de La Tierra for geotechnical borehole drilling to support the design of Sunset Road between I-10 to River Road. One lane of the path on the south bank will be closed March 11, 8 a.m.-5 p.m. and March 12, 8 a.m.-noon. The north bank will be affected March 12, noon-5 p.m. and March 13, 8 a.m.-5 p.m.

    Santa Cruz River Park  

    Grant to Prince: The Pima County Regional Flood Control District plans to remove approximately 140,000 cubic yards of sediment from the bed of the Santa Cruz River channel between the Grant Road and Prince Road alignments. The work will tentatively begin Jan. 15 and could last up to three months. Work will take place Monday through Friday from approximately 7 a.m. to 5 p.m. Loop users should plan on using the east bank path during the work week for the duration of the project. The Loop will be open on the weekends. 

    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.
