County Line Road set to start on Monday

A phased construction approach will be used to allow one lane of traffic to be maintained in each direction during the project, according to the city, and currently no full road closures are anticipated.

Construction on County Line Road between Ninth and 17th Avenues is scheduled to begin Monday. The approximately $3 million project will widen County Line Road to accommodate auxiliary turn lanes and on-street bike lanes, as well as construct various intersection improvements, according to a city news release.

The work is slated to be complete in April 2021, with an anticipated shutdown over the winter months. 

Longmont has contracted with DeFalco Construction for the planned improvements, which include:

  • Limited widening of County Line Road

  • Left-turn lanes installed for the entire length of the project

  • Trail connections at Jim Hamm Nature Area

  • Sidewalk improvements along the west side of County Line Road from the Spring Gulch #2 Greenway (currently under construction) to 17th Avenue

The project is being paid for primarily from the city’s .75-cent Street Fund Sales and Use Tax.

A phased construction approach will be used to allow one lane of traffic to be maintained in each direction during the project, according to the city, and currently no full road closures are anticipated.  To the extent possible, work will be coordinated with Phase 2 of the Spring Gulch #2 Drainage and Trail Improvement project using existing traffic patterns, according to the city. A bicycle detour route that is already in place for the Spring Gulch #2 project will be maintained for this project.

Alternate routes are encouraged to avoid construction delays and lane closures. View project information and traffic impacts at bit.ly/county-line-road-improvements.
