Northwest Corridor EIS

— filed under: Environmental, Denver Metro Area (Region 6), Library

Northwest Corridor Transportation and Environmental Planning Study - July 2008 - In 2003, the Federal Highway Administration (FHWA), in cooperation with the Colorado Department of Transportation (CDOT), initiated a National Environmental Policy Act (NEPA) process to study the need, merits, and possible impacts of potential transportation improvements in the Northwest Corridor of the Denver metropolitan area. The Notice of Intent to prepare an Environmental Impact Statement (EIS) appeared in the Federal Register dated July 21, 2003, and identified the proposed action as: “an improved connection between the western terminus of the Northwest Parkway in Broomfield County and the SH 58, I-70, or C-470 freeway systems to the south in Jefferson County. This connection is considered necessary to address the need for system linkage, to provide for existing and projected transportation demand, to improve safety, and to enhance modal interrelationships, within the Northwestern Quadrant of the Denver Metropolitan Area.”
