College and Trilby Construction to resume in March, 2025#
The City of Fort Collins Engineering Department, in coordination with the City's contractor, Zak Dirt, Inc. has postponed construction of the College/Trilby intersection until March, 2025.
College/Trilby Intersection Improvements#
After several years of planning and development, the City of Fort Collins is beginning a major reconstruction of the U.S. 287/College Avenue and Trilby Road intersection.
After reconstruction the intersection will feature dual left turn lanes from College Avenue to Trilby Road, right turn lanes for each direction of travel, and a widened Trilby Road approach to College Avenue.
The reconstructed intersection will improve safety for current and future traffic levels and growth continues in the region and will create a safer intersection for all users.
Background#
Reconstruction of the intersection of Trilby Road and U.S. 287/College Avenue has been a priority for the City as development and traffic continue in Northern Colorado.
The City recently completed an Arterial Intersection Prioritization Study that identified traffic safety and congestion problems at this intersection.
Safety concerns include high frequencies of approach turn and rear-end crashes. Operational concerns include high volumes on north-south legs and increasing volumes on east-west approach legs, often exceeding the capacities of the single left turn lanes given the available green light times. Bicycle and pedestrian safety and accessibility are also concerns at the intersection.
The City’s Master Street Plan also calls for Trilby to eventually be a four-lane arterial road between Shields Street and Timberline Road. This reconstruction would accommodate a future widening of Trilby.

Schedule#
See the project's timeline below:
- First construction phase
-
The first construction package was completed during summer 2024, installing a new retaining wall near the southwest corner of College Ave. and Trilby Ave. This phase had little to no traffic impacts.
- Second construction phase
-
The second phase will involve utilities and subsurface work. This phase will have significant traffic impacts at the intersection and in the area adjacent to the intersection, and is expected to last 4-5 months. More information will be published on this page when available.
- Final construction phase
-
The final construction phase involves surface and streetscape reconstruction and closely follows the subsurface work. Phase three will see continued traffic impacts and is expected to last 4-5 months.
Funding#
This project is expected to cost between $12-14 million.
Funding will come from Colorado Department of Transportation (CDOT) and Federal Highway Administration (FHWA) grants, the City's Transportation Capital Expansion Fee, and contributions from developments.
November 14, 2023 Public Meeting#
The City and project partners hosted an open house style public information session about planned improvements to the College/Trilby intersection on Nov. 14, 2023. Here are the informational poster boards displayed at that meeting:
March 3, 2022 Public Meeting#
