US 6 & Heritage Interchange Design
The City of Golden, in cooperation with Jefferson County and the Colorado Department of Transportation, has held a number of public input meetings for the US 6 and Jefferson Pkwy/Heritage intersection. We have had great participation and input from the public. Below are the preferred options for traffic and for multimodal solutions to the interchange.
The preferred traffic alternative is a dual roundabout. This alternative will have standard roundabouts at each side of the bridge over a lowered US 6 with Heritage Rd. with Jefferson Parkway staying at about current elevations. Over 90% of the people at public meetings preferred the dual roundabout alternative.
The preferred multimodal alternative has a separate lid for pedestrians and bikes that goes under Jefferson Parkway and the US 6 ramps. This alternative features improved natural landscaping similar to the US 6 and 19th interchange with berming to remove the US 6 traffic from the crossing experience and wide bright tunnels to enhance openness and safety. There was more than majority support for this design for multimodal connections.
The final design features combined traffic and multimodal preferred alternatives. It includes double roundabouts to accommodate traffic and separate offset multimodal lid for pedestrians, bikes and other uses. A complete summary of the alternatives considered and a summary of the public meetings can be found on Guiding Golden at www.guidinggolden.com/us6-and-heritage-interchange-design.
