U.S. Highway 287/Midway Boulevard Intersection Improvements

U.S. Highway 287/Midway Boulevard Intersection Improvements

Location: Broomfield, Colo.

Client: City and County of Broomfield, Colo.

Burns & McDonnell recently completed preparation of the design, right-of-way plans and construction documents for improvements to the intersection of U.S. Highway 287 and Midway Boulevard, including the widening of Midway Boulevard between U.S. 287 and Alter Street.

The city and county of Broomfield and the Colorado Department of Transportation (CDOT) are jointly funding this federal-aid safety improvements project. The proposed improvements, which will add a designated through lane and protected double left-turn lanes for westbound traffic on Midway Boulevard, include installation of two new traffic signals, a raised median to control traffic turning movements, utility relocation, modifications to existing business access, and landscaping and irrigation system improvements. The designated through lane and geometric improvements to the intersection will eliminate the split phasing for the Midway Boulevard traffic signal.

  • Field surveys
  • Right-of-way plats and easements
  • Geotechnical investigations
  • Phasing and traffic control plans
  • Environmental clearances (MESA)
  • Design and contract documents for all proposed facilities
  • Pavement marking and signing plans
  • Signal plans

The design has required extensive coordination with both the city and county of Broomfield and CDOT in determining right-of-way and easement acquisition, environmental clearances, utility relocation and protection, and construction traffic control. The key to this challenging project is to improve the safety and efficiency of this highly used arterial intersection while minimizing construction time and disruption. The improvements will require the location and protection of several utilities including large diameter waterlines, underground electric, fiber optic, telephone and gas lines.
