The City of Boulder Open Space and Mountain Parks (OSMP) has completed trail improvements along the main section of the Cottontail Trail that is part of the Longmont-to-Boulder Regional (LoBo) Trail. That section of trail is currently open and will remain open with the exception for short maintenance closures later this year.
Construction of the Cottontail Trail north of Lookout Road and east of the Gunbarrel Estates neighborhood resumed in January, 2022. That section of the Cottontail Trail remains closed and will be reopened following the completion of trail construction, which is expected to be completed in early-June - weather permitting.
Construction along that section of the Cottontail Trail was delayed last year because the contractor that began trail work told the city it was no longer able to continue construction activities.
