Federal Boulevard & 69th Bridge Replacement over BNSF & RTD Railroads

Project Background

From February 2015 through June 2017, CDOT reconstructed a half-mile portion of Federal Boulevard (US 287) from W 67th Avenue to West 70th Avenue, through the City of Westminster and Adams County.

The project improves traffic flow and safety by eliminating the pinch point caused by the narrow existing bridge through the construction of a wider bridge that will accommodate an additional through-lane in each direction.

The reconstruction of this area included the replacement of a structurally deficient and functionally obsolete bridge over the Burlington Northern Santa Fe (BNSF) Railroad and RTD Railways. The new bridge accommodates the RTD Eagle P-3 Commuter Rail Line underneath, and was built wider and longer.

The project also included:

• extensive earthwork at the bridge approaches.
• extensive retaining walls.
• an asphalt overlay.
• safety improvements.
• an improved storm sewer system for better roadway drainage.
• new lighting to illuminate the recreational path underneath the bridge.
• ADA curb ramps.

As part of the project, CDOT also constructed enhancements and aesthetic improvements for the City of Westminster that tie into work occurring for the Westminster Station Transit-Oriented Development adjacent to the project. These enhancements include:

• decorative fencing and pedestrian railing.
• new, wider sidewalks on each side of Federal Boulevard.
• raised median planter with Westminster city logo and future sculptures.
• a new signal at Westminster Station Drive to access future RTD Eagle-P3 commuter rail station.
• improved steel fencing with water jet grass blades over bridge.
• additional lighting for Little Dry Creek pedestrian trail under new bridge.
