Timberline Road 2021 Widening Map

Continued growth in southeast Fort Collins has led to increased traffic on Timberline Road, which is an arterial road in the city.  Timberline Road is a major thoroughfare for Fort Collins residents, and serves as a significant regional connection for Northern Colorado communities. 

Widening of Timberline to Trilby Road is part of the City’s Master Street Plan and will reduce congestion, improve safety, and enhance bike and pedestrian connections along the corridor.

Project Description and Goals#

This project will reconstruct South Timberline Road from Stetson Creek Drive to Zephyr Road to the City’s four lane arterial roadway standards. Zephyr Road to Trilby Road will be restriped to include two northbound lanes and one southbound lane.  Planned improvements include intersection improvements at Kechter Road and Zephyr Road, multi-modal accommodations, raised medians and center turn lanes, access control, landscaping improvements, and roadway improvements. A pedestrian underpass crossing Timberline Road will also be constructed near Bacon Elementary School.

This project serves to build upon the development improvements that have been completed along the corridor.  This project will improve safety, reduce congestion, and provide improved accommodations for alternate travel modes.


Construction is beginning in December 2021 on a box culvert and pedestrian underpass for the future Mail Creek Trail.

Construction for the widening of Timberline Road is expected to begin in late April 2022.

Current Funding#

This project is estimated to cost around $8 million. Funding comes from the Transportation Expansion Capital Fee fund, developer contributions, and federal funds.
