I-76 and Bridge Street Interchange Project
Environmental Assessment of a New Interchange on I-76 at Bridge Street is Now Available for Public Review
BRIGHTON, Colo.—The City of Brighton, Colorado, has released an Environmental Assessment document for public review. Preparation of the I-76 and Bridge Street Interchange Project Environmental Assessment has been a cooperative effort among the Federal Highway Administration (FHWA), the Colorado Department of Transportation (CDOT), and the City of Brighton.
This document analyzes permanent and temporary impacts to the natural environment and built surroundings resulting from construction of a new highway interchange at I-76 and Bridge Street in Brighton. The project would add a full interchange on I-76 at Bridge Street with two roundabouts on Bridge Street—one east of the highway and one west of the highway—to simplify getting on and off of the highway. Other types of interchanges were studied as part of this project; however, the two-roundabout interchange was recommended as the preferred alternative.
The National Environmental Policy Act of 1969 (NEPA) requires all federally funded projects that may have an impact on the environment to be analyzed through a rigorous process that allows the public to understand and comment on the benefits and impacts of the project. The Environmental Assessment has been prepared in accordance with NEPA, and is available for public review and comment for 30 days, starting February 12, 2015, and ending on March 14, 2015.

The proposed interchange is moving forward and the environmental clearance phase is well underway. Alternative designs have been refined based on community input and local representatives. Roundabout designs are supported by the school district, parks and recreation department, emergency response, and police department for the following reasons: improved efficiency, traffic relief at the Bromley Lane and I-76 roundabout, improved school bus and emergency response routes to access facilities along Bridge Street, and the opportunity to include landscaping elements in the final design. The Environmental Assessment will be released to the public this summer. Check this website to stay informed of opportunities to comment and discuss your thoughts with the project team.

The System Level Study for the I-76 and Bridge Street Interchange were approved by the CDOT transportation commission on October 17th, 2013. The study documents the need and operational acceptability for the proposed interchange. This approval is a critical milestone for the interchange. The next steps include completion of the Environmental Assessment (EA) and decision document following a public comment period. Then, CDOT will enter into an intergovernmental agreement (IGA) with the City of Brighton for the construction, maintenance and operations of the facilities associated with the interchange.
