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.
However, construction along the section of Cottontail Trail between Lookout Road and the LoBo trail – east of the Gunbarrel Estates neighborhood – is delayed because the contractor that began trail work has told the city it is no longer able to continue construction activities. OSMP is working as expeditiously as possible to restart trail construction, which requires a contractor with specialized tools and equipment to construct engineered drainage crossings and site grading. This section of the Cottontail Trail will remain closed as the area is an active construction site that presents safety risks to visitors.
Because the city must equitably select a new contractor through a procurement process which will require new bids from other vendors, OSMP cannot provide a specific date for when trail work will restart. OSMP recognizes this trail section's importance to community members, and the department appreciates their patience while we secure a contractor to complete trail construction.
