Background
The bridge that funnels Dry Creek #3 underneath Baseline Road east of Baseline Reservoir is in need of replacement. Public Works will replace the existing bridge with a larger structure that will increase drainage capacity. In addition, crews will replace the guardrail, restore the creek’s alignment, improve neighboring wetlands, and repave and restripe the project area.
Timeline
The project will take place in two phases. During phase one, in order to complete the bridge project, Xcel Energy will need to relocate a gas main and nearby overhead electrical wires. During phase two, Public Works and our contractor will complete the bridge installation.
- Phase I – Xcel – March or April 2026 through spring of 2026
- Phase II – Public Works – Fall/Winter 2026 through January 2027 (exact dates still to be determined)
Travel Impacts
Both phases of construction will require a full closure of Baseline Road for two months each. Travelers on east and westbound Baseline Road will be detoured to South Boulder Road. See a map of the detour and project location.
Trailhead Closure
Dry Creek Trailhead will also be closed during the county’s portion of the project.
