Beginning in February 2015, the Colorado Department of Transportation (CDOT) sponsored by the Bridge Enterprise Program will begin reconstructing a one half mile portion of Federal Boulevard (US 287) from W 67th Avenue to W 70th Avenue through the City of Westminster in Adams County. The reconstruction of this area includes the replacement of a structurally deficient and functionally obsolete bridge over the Burlington Northern Santa Fe Railroad. The new bridge will accommodate the new RTD Eagle P-3 Commuter Rail Line underneath and will be built wider to meet phasing requirements for maintaining two lanes in each direction during construction. The project will also include extensive earthwork at the bridge approaches and new retaining walls as well as an asphalt overlay, safety improvements, storm sewer expansions for better roadway drainage, and enhancements to the recreational path underneath the bridge.
The bridge and associated construction will be completed in three phases. The first traffic phase, which will be implemented in early to mid-2015, will put all four lanes of traffic on the east side of the road to assist with construction on western portion of the bridge and approach. Throughout the duration of phased construction, a reduced speed limit of 35 mph will be observed in the area, lane and shoulder widths will be reduced, and lane changes will be limited. For the entirety of construction, all business accesses will remain open and accessible to the public. The sidewalk on Federal Boulevard will remain open, however the recreational path underneath the bridge will be closed for the duration of construction. Limited lane closures may occur during non-peak periods of travel. During construction, the public is advised to use extra caution through the work zone.
As part of the project, CDOT and Hamon Infrastructure will be constructing 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 aesthetic fencing and pedestrian railing, sidewalk additions and improvements, a raised median with planters, and a new signal at 69th Avenue.
This construction project will be completed in late 2016.
