October 2006 - The City of Wheat Ridge identified the area southwest of the Interstate 70 / State Highway 58 (I-70/SH 58) interchange as an urban growth area with potential office, commercial, and retail land use to begin development in the next several years (City of Wheat Ridge 2005). Land use in the area southwest of the I-70/SH 58 interchange is changing from previous aggregate mining to retail and commercial use, as identified in the City of Wheat Ridge Comprehensive Plan (City of Wheat Ridge 1999, as amended in 2005). The proposed change in land use, in conjunction with regional growth, will affect traffic operations at this interchange and on the local arterial streets in the vicinity of the interchange.

The proposed I-76 and Bridge Street Interchange Project is located in Brighton, Colorado, in Adams County. The City of Brighton proposes to construct an interchange at I-76 and Bridge Street on the eastern side of the city. The proposed interchange would provide an opportunity to increase regional east-west connectivity across State Highway 7. This regional connectivity will become increasingly important with future population growth and increased travel demand.

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.” Keywords: Studies, Non-HighwaysNo publisherEnvironmentalDenver/Central Colorado (Region 1)Library2010/01/29 13:05:00 GMT-6FolderI-70 East Environmental Impact Statement (EIS)
https://www.codot.gov/projects/studies/study-archives/i-70-east-environmental-impact-statement-eis.url
In July 2003, CDOT and Denver’s Regional Transportation District (RTD) began a joint study effort called the I-70 East Corridor Environmental Impact Statement (EIS). An EIS is typically a three to five-year decision-making process required before any major federally-funded transportation project can be built. The EIS ensures that issues affecting the community and the environment are identified and considered before making a final decision. The process is conducted by local, state, and federal agencies and is a requirement of the National Environmental Policy Act (NEPA). The purpose of the I-70 East Corridor EIS was to improve transportation along the I-70 highway corridor from I-25 to Tower Road and to explore potential rapid transit options from Downtown Denver to Denver International Airport.
