North Shields Street (County Road 17) Corridor Improvements

Larimer County Project No. 301
Replacement of Bridge No. 17-0.5-48 over the Poudre River and
Road Reconstruction of North Shields Street (County Road 17) from the Arthur Ditch to Willox Lane

Last Updated:  February4, 2015


North Shields Street (County Road 17) is a major arterial connection between Fort Collins and northern portions of unincorporated Larimer County. Concerns on this stretch of roadway include:

  • Structurally deficient* and narrow river bridge with poor roadway approaches
  • Heavy vehicle, bicycle and pedestrian traffic
  • No turn lanes
  • Poudre River Trailhead poorly defined
  • No safe parking
  • No bicycle/pedestrian facilities
  • High number of access points
  • Relatively high number of accidents

Larimer County has applied for and received three federal grants to make improvements to North Shields Street (County Road 17) from just north of Vine Drive to Willox Lane in northwest Fort Collins. One grant is to replace the bridge over the Poudre River, another is to make improvements to Shields Street between the Arthur Ditch and Willox Lane and the third is to provide a trailhead/parking area for the Poudre River Trail.


Construction is in full swing. City of Fort Collins crews began work in early December on the installation of a new sewer main running north from just north of Vine to Willox street. In January work on the sewer and several other utility relocations required Shields street to be closed to through traffic. Utility crews are still hard at work clearing the way for the road and bridge improvements.

Duran Excavating will be performing the bridge and road construction for Larimer County. Crews began onsite activities February 2nd. The first pieces of work will be the demolition of the Poudre River bridge and the Arthur Ditch crossing. Construction will then immediately proceed to drilling the deep foundations of the bridge and forming of the abutments.

The County is excited about the start of this project and look for a completion in August.


This is an important component of the project and County staff encourage input and feedback from citizens.

Project Newsletters will be posted when new information is available.
