Upcoming Roadway and Sidewalk Closure on 18th Street between Broadway and Euclid – June 2 to August 1, 2025

During a campus waterline replacement project, 18th Street between Broadway and Euclid will undergo phased closures for new waterline installation and roadway restoration. 

Proposed construction schedule (subject to change based on field conditions):

From June 2 to July 11 the southbound lane from Lot 204 to Broadway will be closed (one northbound lane will remain open to allow access into Lot 204 and the Wardenburg lot). 

From July 11 to July 25 there will be phased closures of 18th Street to allow access to lots 204, 310 and 325. Various traffic patterns will be utilized; vehicles and pedestrians should follow posted signage in and around the construction zone.

From July 26 to August 1, there will be a complete closure of 18th Street from Broadway to Euclid. There will be no access to lots 204, 310 and 324 during this phase. Folks needing vehicle access to Wardenburg during this time will need to access Wardenburg Drive via Colorado Ave (lot 360 entrance) to Libby Drive to Baker Drive to Wardenburg Drive. 

Sidewalks in the area will also be closed during construction. Impacted buildings include Music, Wardenburg, CASE, and parking lots 204 and 310. Please refer to posted signage and reroute maps for CU Buff Bus summer service.
