SH 82 Grand Avenue bridge environmental assessment & section 4 (f) evaluation
SH 82 Grand Avenue bridge environmental assessment & section 4 (f) evaluation
The Grand Avenue Bridge project is being proposed to improve the connection from downtown Glenwood Springs, Colorado, across I-70, the Colorado River, and the Union Pacific Railroad (UPRR) to the historic Glenwood Hot Springs area. The State Highway (SH) 82/Grand Avenue Bridge is the gateway to Glenwood Springs, Glenwood Canyon, the Roaring Fork Valley, and Colorado's western slope communities. It serves as a vital link for local and regional travelers. This project proposes replacing the existing four-lane bridge with a new four-lane bridge on a modified alignment., Description based on online resource; title from PDF cover; (viewed July 2015), CDOT Project No.: FBR 0821-094 (18158)

SH 82 Grand Avenue bridge finding of no significant impact and section 4 (f) finding
The Grand Avenue Bridge project will replace the existing Grand Avenue Bridge with a new bridge that begins at the current southern touchdown point, then curves to the west to touch down north of the river at a location west of the existing bridge. The pedestrian bridge adjacent to the highway bridge will also be replaced on the same general alignment as the existing pedestrian bridge. The project will improve the north and south connections for both bridges, and will change the 6th Street/Laurel Street intersection to a roundabout configuration as part of the SH 82/Grand Avenue Bridge north connection improvements., Description based on online resource; title from PDF cover; (viewed July 2015), CDOT Project Number: FBR 0821-094 (18158)

"December 2010.", The City of Glenwood Springs (City), the Colorado Department of Transportation (CDOT), the Roaring Fork Transportation Authority (RFTA), and Garfield County have identified the need to plan for transportation improvements along the State Highway 82 (SH 82) Corridor in Glenwood Springs. It is recognized SH 82 is the City's "main street," while also serving as the main regional transportation artery serving the Roaring Fork Valley; therefore, strategies to address future regional and local transportation demand must be developed within the context that any transportation strategy will have an impact on one or more areas of the City or future travel times through the Corridor., Online resource; title from PDF cover (viewed January 2018)

Safety performance functions for freeway merge zones
Safety performance functions for freeway merge zones
This report documents the results of a research project to support CDOT in the area of Safety Performance Function (SPF) development. The project involved collecting data and developing SPFs for ramp-freeway merge zones categorized as isolated, non-isolated and weave. For each of these three categories, data for the period 2007 to 2011 were collected at sites selected to ensure statewide geographical representation and coverage of the range of traffic volume and other variables in each category. Separate SPFs were developed for Total, fatal+injury (FI) and Property Damage Only (PDO) crashes., Craig Lyon, Bhagwant Persaund, David E.
