The Colorado Department of Transportation (CDOT), with assistance from their consultant, Wilson & Company, conducted a corridor optimization study for 2 State Highways: 83 and 86. The intention was to assess how to meet future travel demands in two corridors while considering modal mix, capacity, access, land use, cost, and funding options.
As part of this study, CDOT offered local jurisdictions an opportunity to provide input into this regional and statewide planning process. Of concern to Parker, was State Highway 83 (Parker Road) through the Town's Urban Service Area, more specifically from Cottonwood Drive on the north to Stroh Road on the south. To assist the Town with this effort, EDAW was brought on to provide illustrations that would represent the Town's vision during this process.
Parker Road Principles
Specific principles were integrated in the study and were the basis for the Town's recommendations:
Regional goal to establish alternative parallel routes
A limited access freeway is not acceptable
Current noise level is not acceptable
Parker Road should not be widened
Speeds should be lowered
Town control of traffic signals
Five alternatives were initially considered:
Widen Parker Road
Chambers Road Bypass
Parker Road and Twenty Mile Road
Twenty Mile and Dransfeldt Road
Of these, 2 alternatives, as outlined below, were carried forward and were supported for incorporation into the CDOT Study.
Develop a one-way couplet along the existing Parker Road and Twenty Mile Road dividing north of Indian Pipe on the south and converging south of E-470 on the north. View One-Way Couplet Map (PDF).
Develop parallel parkways using an Intelligent Traffic System (ITS) to guide traffic to the fastest route, dividing north of Indian Pipe on the south and converging south of E-470 on the north. View Parallel Parkways Map (PDF).
