Power Trail/Mail Creek Trail Overpass Connection#


Project Map

The Power Trail is a recreational and commuter bike trail running north and south through the City of Fort Collins. At the north end it connects with the Spring Creek Trail, and at the south it connects with the Larimer County and City of Loveland trail networks. The trail runs parallel to the Union Pacific Railroad tracks.

Because of its proximity to the railroad tracks, access to the trail from the east is limited to where roads cross the tracks. Between Harmony Road and Trilby Road, there is a 2-mile section with no access from the east. There is significant demand for access in this section because of nearby residential neighborhoods, schools, and businesses. There is also evidence of people crossing the tracks in unauthorized locations to access the trail. With planned future residential developments east of the tracks near the project location, it is expected that demand will increase significantly.

Project Description and Goals#

The Siphon Pedestrian Overpass Project will design and construct a trail bridge over the railroad tracks and a trail connection to Timberline Road, about halfway in between Harmony and Trilby. The trail connection will follow the south bank of the Mail Creek Ditch and the north edge of two planned residential developments. The project will provide access to the Power Trail from the east, eliminating the need for trail users to travel north to Harmony or south to Trilby.

The City was awarded a State of Colorado Multi-Modal Options Fund grant for design and construction. The project is a partnership between the City’s Engineering Department and Park Planning & Development Department.


  • City Staff have teamed with a design consultant firm to design the bridge and trail connection. Design is anticipated to be complete in late 2022.
  • Construction is tentatively scheduled for 2023.
