Trail Crossing to Rocky Flats National Wildlife Refuge

Project Description

Jefferson County, County and City of Broomfield, Boulder County, City of Boulder, City of Westminster, City of Arvada, the U.S. Fish and Wildlife Service (FWS), and the Federal Highway Administration, Central Federal Lands Highway Division (FHWA-CFLHD), are proposing two, grade separated trail crossings into the Rocky Flats National Wildlife Refuge (ROFL). The eastern crossing would extend the Rocky Mountain Greenway trail, which currently terminates in the Broomfield open space, by crossing Indiana Street. The northern crossing would extend the Coalton and High Plains trails by crossing State Highway 128. This project will be combined with the CO FTFW ROFL TRAILS (1) Rocky Flats National Wildlife Refuge Trails project, which will build trails within the interior of ROFL.
