We’re excited to announce a major update on the Marshall Mesa Trailhead Project! Starting as early as the end of October, the main Marshall Mesa trailhead will be closed for approximately a year to undergo a significant earth-moving project. The first phase will focus on reducing coal seam fire risks by excavating up to 30 feet below the surface, cooling the underground materials, and then restoring the earth. Once completed, the City of Boulder will build a brand-new improved parking lot and trailhead.
Thanks to BMA’s close collaboration with the City of Boulder, we’ve secured approval for a temporary trail around the construction site. This ensures that despite the closure, riders can still access the trails via the main trailhead and avoid the need to ride on Highway 170 to the old trailhead. The temporary trail will begin at the current crosswalk, run parallel to Highways 170 and 93, and reconnect with the Coal Seam Trail.
Construction and the trailhead closure are expected to begin by late October. BMA has scheduled a trail building day on Monday, October 14, to create the new access trail—join us and volunteer to make it happen!
