Muller assisted CDOT Region 3 with the design of intersection improvements at the intersection CO 340 and Redlands Parkway in Grand Junction. The intersection is in the western portion of Grand Junction known as Redlands. The project consisted of reconstruction of the existing signalized intersection to a new modern roundabout. The City of Grand Junction staff prepared a conceptual design of a modern roundabout. The Muller team provided review and validation of the roundabout concept, proposed modifications to the design, then prepared preliminary and final plans, specifications and estimates for its construction.

The roundabout is a unique design with two quadrants that are single lane and two that are two lanes. The unique laneage favors a heavy east-to-north turning movement at the intersection. The reciprocal south-to-west movement utilizes a bypass lane. The roundabout was constructed with Portland cement concrete pavement and the design included a jointing plan for the varying geometry of the intersection.

One of the project challenges was Goat Wash, a drainageway along the westerly side and parallel to Redlands Parkway through the project area. Work included hydrologic and hydraulic analysis of Goat Wash and extending and lining of the 84-inch CMP pipe along with inlet and outlet protection for improved hydraulic performance.

This project required a public involvement process that included two open house meetings. Muller supported CDOT with graphics and project representatives attending the meetings in Grand Junction. Muller also prepared mailer invitations, sent them to area residents, businesses and landowners, and prepared comment sheets for meeting attendants to use at the meeting to document their input.

As this project progressed, CDOT added additional work for an overlay of CO 340 or approximately 0.9 mile west of Redlands Parkway. The overlay project was combined with the intersection project.
