Rock Creek Parkway construction update

Published on July 14, 2026

Detours in place starting Wednesday, July 15

Starting July 15, Rock Creek Parkway will close between South Indiana Street and Enterprise Street; this includes the closure of South 88th Street up to Shamrock Drive. The closure allows crews to complete corridor improvements before Boulder Valley School District students return to school on Aug. 12.

Emergency services will continue to have access through the construction zone. If evacuation orders are issued, residents will be able to use emergency access points on Lanterns Lane at Promenade Drive, East Weldona Way at 88th Street, and through the construction zone as needed.
