Washington Street Intersection Improvements 

Washington Street Intersections Improvements

Northglenn, CO

JR Engineering led Design-Build project.  JR teamed with Asphalt Specialties and WL Contractors for design and construction management of a 5 lane major arterial with intersection improvements including asphalt paving, curb and gutter, sidewalk, traffic signals, striping, and landscaping.  Services included preliminary construction plans, design survey, right-of-way maps, utility design survey, pavement design, traffic engineering, utility relocation coordination, legal exhibits, roadway construction, landscaping, traffic signal construction, construction staking, materials testing, and as-builts.  During construction, a major Qwest utility vault and fiber-optic transmission lines were discovered to be in conflict with the proposed widening.  JR was able to redesign portions of the roadway to avoid the conflict without increasing the overall project costs.
