US 287 at Lamar

In the early 1980's, City of Lamar and Prowers County officials began developing a vision for an alternate truck route around the City of Lamar. They believed that a truck route taking trucks off of US 287 would improve traffic safety in the community by reducing the current volume of truck traffic along Main Street through the city. A Task Force of local business owners and officials was created to promote the vision of a truck route. The Task Force approached the Colorado Department of Transportation (CDOT) and requested that such a truck route be included in long range planning efforts. Keywords: Studies, US Highways
