US 6 and 19th Street Interchange—City of Golden

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 interchange to replace the existing signalized intersection with a $25 million modified diamond interchange featuring a city park and multi-use trails built on the first highway lid in Colorado. Muller completed traffic operations analyses, including Synchro and VISSIM modeling for the interchange alternatives along with the required documentation to obtain CDOT permits for the new 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.
