Dillon Road/West 144th Avenue Improvements

Broomfield, Colorado

Increasing traffic volumes in the area caused traffic congestion and delays during the peak hours, with the Broomfield Transportation Master Plan anticipating between 30,000 and 35,000 vehicles per day in the corridor by 2030. The new template for this 4.1-mile urban arterial roadway improvement included four through lanes, two in each direction, a raised or striped median, bike lanes, curb and gutter with new storm sewers, roadway lighting, and new traffic signals. A new ten-foot detached multi-purpose trail runs from US 287 to Sheridan Boulevard. Near Sheridan Boulevard, a new box culvert now encloses 1,500 feet of the community ditch adjacent to the widened roadway. All-in-all, this project provides 3.1 miles of multi-use trail, upgraded 10 intersections with signal pole foundation designs, building a 150-foot long retaining wall, and widening a box culvert to carry Rock Creek under the roadway. From Aspen Street to Sheridan Boulevard, the project includes a frontage road along the north side of Dillon Road/West 144th Avenue to control access and provide safe ingress and egress to residential properties. Muller provided planning, design, and construction support services.
