The Lariat Loop Scenic & Historic Byway is a 40-mile (64 km) route in the foothills between Golden, Morrison, and Evergreen about 20 miles (32 km) west of Denver, Colorado. The byway includes portions of State Highway 93 between Golden and Morrison, State Highway 74 from Morrison to Evergreen via Bear Creek Canyon, and the same road north to Interstate 70, which bisects the loop. The Lariat Trail connects Golden with the top of Lookout Mountain and Lookout Mountain Road completes the loop back to Interstate 70. This route formed the foundation for the surrounding 150-square-mile (390 km2) area's designation as a Colorado Heritage Area in 2000; the Byway was so designated by the Colorado Dept. of Transportation and Governor Owens in April 2002. The Lariat Loop connects to the Mount Evans Scenic Byway via Squaw Pass Road.
