March 2026: 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.

A community information session will be held at the Erie library on Wednesday, April 29 at 6:00 PM. Translation services in Spanish and Nepali will be available. The session will also be livestreamed on the Boulder County YouTube channel.

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

Eligibility

Data from the 2026 Boulder County Community Survey shows that 29% of respondents rated this service as “important” or “very important.” The survey, conducted every two years, received 6,585 responses from residents across the county.

Volunteers contributed over 14,609 hours to this program last year. The Housing & Human Services coordinates with 18 nonprofit partner organizations throughout Boulder County to deliver services.

Community Impact

The project includes improvements along South Boulder Road between Erie and the intersection with Flagstaff Road. Construction is scheduled to begin in July 2026 with completion expected within 7 months.

Residents in the Erie area should note that service boundaries may differ from city limits. For properties in unincorporated Boulder County, contact Housing & Human Services at (303) 441-7266 to verify eligibility and requirements.
