Route description
SS 7 in south St. Vrain Canyon, near Lyons, July 2012.
From Estes Park, SH 7 climbs into the mountains of southwest Larimer County and skirts the east side of Rocky Mountain National Park, providing the closest vehicle approach to the popular trailhead to the summit of Longs Peak. Near the community of Raymond it intersects State Highway 72, which takes the Peak to Peak Scenic Byway designation with it to the south, while SH 7 turns to the east and follows South St. Vrain Creek downstream onto the piedmont at Lyons, where it intersects US 36. South of Lyons it is concurrent with US 36 along the base of the foothills to Boulder. (This section is signed only as US 36.) It is also concurrent with State Highway 119 on 28th Street within Boulder. It runs straight east from Boulder as the extension of Arapahoe Avenue to U.S. Route 287 (US 287) north of Lafayette, jogging one mile (1.6 km) to the south while concurrent with US 287, then going due east again, as Baseline Road, to I-25. East of I-25 it jogs one mile (1.6 km) south, then due east as 160th Avenue (part of the Greater Denver street numbering system) through Brighton to I-76 in the eastern part of Brighton.
The route was established in the 1920s. It began at Estes Park and traveled south to Lyons, then south to Boulder. It then continued to its terminus at U.S. Route 87 (now also I-25) east of Lafayette. The route was paved from Boulder to Lafayette in 1932 and from Estes Park to Lyons in 1936. In 1939, the route was extended southeast to Brighton, where it met U.S. Route 6; this extension was paved by 1946. In 2006, the section on Broadway between US 36 and Canyon Boulevard in Boulder was turned back to the City of Boulder, and SH 7 was rerouted to be concurrent (unsigned) with US 36 on 28th Street through Boulder.[2]
