Niwot Loop Concrete Bridge Approaches

Boulder County Parks & Open Space (BCPOS) Department is seeking proposals for Concrete Bridge Approaches near the Niwot Loop Trailhead. The property address is 7901 Mineral Rd Unincorporated, Niwot, CO, 80503. The current crusher-fines approaches to the bridges have proven unsustainable due to the steep gradation leading in and out at both bridge locations. Trail sediment encroaches and settles onto the bridges which raises public safety concerns and premature degradation of the bridge decking. The proposed concrete improvements will ensure proper drainage, long-term trail sustainability, and improved accessibility for all trail users including those with mobility challenges.
