Eldora Community Briefing: Boulder Canyon Trail Closure Due to Rockfall Mitigation Work

Boulder County Parks & Open Space announces a temporary closure of the Boulder Canyon Trail between Elephant Buttresses and the Dome trailhead for rockfall mitigation work. Crews will be scaling loose rock and installing mesh netting along a 400-foot section of cliff face above the trail. The closure is expected to last approximately three weeks, weather permitting.

Data from the 2024 Boulder County Community Survey shows that 30% of respondents rated this service as “important” or “very important.” The survey, conducted every two years, received 6,467 responses from residents across the county.

Transportation access remains a key concern. Boulder County’s Via mobility program provides door-to-door transit service for residents in Nederland and surrounding communities who cannot access fixed-route bus service. RTD routes B, J, and BOLT serve major corridors.

Timeline

The Board of County Commissioners will review progress on this initiative at their April 27 business meeting. Agenda items and supporting documents are posted on the Boulder County website 72 hours before each meeting.

The project includes improvements along 75th Street between Nederland and the intersection with Flagstaff Road. Construction is scheduled to begin in August 2026 with completion expected within 14 months.
