Watson Mill Bridge State Park is a 1,018-acre (4.12 km2) Georgia state park located near Comer and Carlton on the South Fork of the Broad River. The park is named for the Watson Mill Bridge the longest original-site covered bridge in Georgia, which spans 229 feet (70 m) across the South Fork of the Broad River. The site is listed on the National Register of Historic Places as the Watson Mill Covered Bridge and Mill Historic District.

The Floor of the Valley Road, also known as the Zion Canyon Scenic Drive, follows the canyon of the North Fork of the Virgin River, also known as Zion Canyon, through Zion National Park, Utah, USA. A precursor to the present nine-mile road was first built in 1916, but was later redesigned by the National Park Service Branch of Plans and Designs to highlight the natural features of the valley while presenting a natural-appearing built environment. The road begins at the south boundary of the park and ends at the Temple of Sinawava.

The historical buildings and structures of Zion National Park represent a variety of buildings, interpretive structures, signs and infrastructure associated with the National Park Service's operations in Zion National Park, Utah. Structures vary in size and scale from the Zion Lodge to road culverts and curbs, nearly all of which were designed using native materials and regional construction techniques in an adapted version of the National Park Service Rustic style. A number of the larger structures were designed by Gilbert Stanley Underwood, while many of the smaller structures were designed or coordinated with the National Park Service Branch of Plans and Designs. The bulk of the historic structures date to the 1920s and 1930s. Most of the structures of the 1930s were built using Civilian Conservation Corps labor.
