The Grand Avenue Bridge project team has worked with the Glenwood Springs community and other stakeholders since April 2011 to develop alternatives for the 6th and Laurel intersection. In May 2013, a revised roundabout option was recommended by the Project Working Group (PWG) as the preferred configuration for the Build Alternative in the Environmental Assessment (EA).
Each intersection alternative has been developed and evaluated based on the project criteria developed early in the process with input from stakeholders and the public. Details of the evaluation criteria and the extensive process to reach a preferred configuration for the intersection are highlighted in a comprehensive brief, now posted on the project’s web site (http://www.coloradodot.info/projects/sh82grandavenuebridge).
The brief provides information and graphics on the range of options for the intersection, including numerous variations of three-, four-, and five-legged roundabouts; four and five-legged signalized intersections; a T-intersection off of the new Grand Avenue Bridge to 6th Street; and many others. Stakeholders submitted ideas that were incorporated into the options that were evaluated against project criteria.
Finally, the brief provides an overview of decision process and how public and stakeholder input influenced it.
Ultimately, the Revised Alternative 3A roundabout was determined to respond to stakeholder concerns and, overall, to be the best of the configurations evaluated. It was presented at the May 30, 2013, Stakeholder Working Group meeting, with the following benefits:
· Removes the separate “T” intersection at 6th Street and W. 6th Street, simplifying traffic movement.
· Creates a longer stretch on 6th Street for parallel parking and frontage to businesses.
· Requires less private property acquisition.
· Refines the locations of sidewalks and pedestrian crossings on the north side of roundabout at streets with lower traffic volumes.
