Detour will be available.

A portion of the Hidden Star Trail located at Niwot Trails open space will be closed for a culvert replacement beginning Monday, March 13. Construction is expected to take a few weeks with an expected reopening date of Friday, April 7. Severe erosion under the Hidden Star Trail pedestrian bridge has created unstable conditions. Staff will install a culvert and repair the bridge supports. Updates will be posted to boco.org/NiwotTrails. For more information, please contact Chris Trujillo at ctrujillo@bouldercounty.org.
