Part of Niwot Loop Trail under repair

A portion of the Hidden Star Trail located at Niwot Trails open space will be closed for a culvert replacement beginning Monday, March 13. A detour around the closed section of the Niwot Loop Trail will allow bikers, runners and pedestrians to continue using the trail.

Construction is expected to take several weeks with an expected reopening date of Friday, April 7. Severe erosion under the Hidden Star Trail pedestrian bridge has created unstable conditions, necessitating the repair.

Boulder County will install a new culvert and repair the bridge supports.
