In addition to 60,000 vehicles, hundreds of residents, cyclists, and Colorado School of Mines students negotiate the US 6/19th Street intersection in Golden each day traveling between neighborhoods and downtown, up Lookout Mountain, and between classes and student housing. Muller Engineering Company designed a new $25 million interchange to replace the existing signalized intersection with the first highway lid in Colorado, featuring a city park and multi-use trails. The project incorporated an extensive stakeholder and public involvement program that included the City of Golden, CDOT, and Colorado School of Mines.
Muller completed traffic operations analyses, including Synchro and VISSIM modeling, for the alternatives along with the required documentation to obtain approval for the interchange. For the final design, Muller prepared geometric design and traffic engineering improvements, using an innovative design to separate vehicle and pedestrian/bicycle traffic without the installation of traffic signals at the interchange ramp terminals.
