South Boulder Road Reconstruction & Panel Replacement Project

Emergency concrete repairs on South Boulder Road west of Cherryvale – No left-turns onto Cherryvale from South Boulder Road

A recent inspection showed significant concrete failures on South Boulder Road west of Cherryvale Road. Emergency repair work will start at 8 a.m. on Monday, Aug. 17, which will require prohibiting left-hand turns from South Boulder Road onto Cherryvale Road in both directions 24-hours a day, until the work is complete in early September. Right-hand turns will be allowed onto Cherryvale Road. South Boulder Road will remain open in both directions, but the road will be reduced to a single lane in both directions for all users. Detours for Cherryvale Road will be established:

  • Travelers seeking to access northbound Cherryvale Road from eastbound South Boulder Road will need to take northbound Foothills Parkway to Baseline Road, then take Baseline east to Cherryvale Road
  • Travelers seeking to access southbound Cherryvale Road from westbound South Boulder Road will need to head north on 76th Street from South Boulder Road to Baseline Road, then follow Baseline west to Cherryvale Road.
