Under contract with Routt County, Drexel Barrell provided the design for the replacement of the Green Pipe Bridge, which provides a crossing of the East Fork of the Williams Fork of the Yampa River on Routt County Road 67. The original “Green Truss Bridge” was built in 1920. This project is federally funded with CDOT Local Agency oversight. Drexel Barrell provided the bridge design, topographic survey, hydrology and hydraulics, grading, drainage, utility, and erosion control plans.
