Washington Street Corridor Study
Matrix has been retained by the City of Thornton to provide professional engineering and design services for the reconstruction of Washington Street from 144th Avenue to 150th Avenue. The project includes 4,200 lineal feet of reconstruction of Washington Street to provide a six-lane street section with a raised landscaped median, bicycle lanes, and a 10-foot sidewalk/trail. The project also includes a significant realignment and improvement of 3,000 lineal feet of Shay Ditch, which is tributary to Big Dry Creek. A new 250 foot long pedestrian underpass and storm drainage conveyance structure is also included at the Washington Street crossing over Shay Ditch.
Significant utility coordination took place with Noble Energy [to accommodate an oil supply pipeline relocation] and XCEL energy [to avoid existing major 230kv transmission towers along the west side of the roadway]. Additional utility coordination included the design of water main facilities and the identification and adjustment of impacted dry franchise utilities. Finally, Matrix supported the City of Thornton with right-of-way and easement documentation for the acquisition of property to accommodate the Washington Street and Shay Ditch improvements.
