Boulder County residents and outdoor enthusiasts have a new reason to celebrate as the Fourmile Canyon Creek Trail Underpass recently connected the Fourmile Canyon Creek Path with the Cottonwood Trail, seamlessly integrating into the Longmont-to-Boulder (LoBo) Trail system. The pivotal project, facilitated by the Public Works and Community Planning & Permitting departments, has been completed after BNSF Railway laid the groundwork with the initial phase of construction back in late 2023. According to Boulder County, a ribbon-cutting ceremony to commemorate the opening will be scheduled this summer, with details forthcoming.
This underpass is a significant addition to the local infrastructure, promising to safely connect northern and eastern Boulder to Gunbarrel, Niwot, and Longmont. Public Works Director Steve Durian, as obtained by Boulder County, expressed his enthusiasm, noting that the completion of this underpass is "instrumental in connecting the trail systems...and in a safe way for trail users without being disruptive to BNSF railroad operations." The underpass not only bridges paths for cyclists and pedestrians, but it also symbolizes the committed efforts to enhance mobility throughout the region.
The project reflects a close collaboration between various entities. Both BNSF and the City of Boulder's Transportation and Mobility and Open Space and Mountain Parks (OSMP) departments were integral to bringing the underpass to fruition. Dan Burke, director of Boulder's OSMP, emphasized in a statement that "The completion of this project is another important step in the City of Boulder’s ongoing partnership with Boulder County to build a more connected trail system—linking people, open space, and communities across the region," as per Boulder County. The interdepartmental cooperation signifies a shared vision to improve and expand Boulder's trail networks.
Users of the new underpass will not only enjoy a safer transit but also witness an urban parkscape thoughtfully integrated into the greater Boulder area. "The city thanks Boulder County and BNSF for their support of this project, and we welcome community members to begin using this important trail connection," Burke said, as obtained by Boulder County, extending an invitation to locals and visitors to explore the newly accessible tracks. As we await further details on the celebratory event, the underpass already stands as a testament to Boulder's dedication to accessible, eco-friendly transportation and community connectivity.
