: Environmental assessment I-70 Floyd Hill to Veterans Memorial Tunnels; The Colorado Department of Transportation (CDOT) and the Federal Highway Administration (FHWA) propose the Interstate 70 (I-70) Floyd Hill to Veterans Memorial Tunnels Project (Project) to improve travel time reliability, safety, and mobility, and address the deficient infrastructure on the eastern portion of the I-70 Mountain Corridor from east of the Beaver Brook/Floyd Hill interchange in the Floyd Hill area through the Veterans Memorial Tunnels to the eastern edge of Idaho Springs. Major elements of the Project include adding a third westbound travel lane on I-70, constructing a missing frontage road connection, adding an eastbound auxiliary lane to the uphill section of Floyd Hill, improving interchanges and intersections, improving design speeds and stopping sight distance on horizontal curves, improving the Clear Creek Greenway, and implementing environmental mitigation for wildlife connectivity, air and water quality, stream conditions, and other strategies. The Project is anticipated to cost about $700 million., lead agencies U.S. Department of Transportation, Colorado Department of Transportation., "July 2021."--Cover., Includes bibliographical references (pages 130-131), Online resource; title from PDF cover; (viewed August 2025)., Project Number: NHPP 0703-445, Project Code: 21912.
