Mount Rainier Roads and Bridges Mount Rainier National Park, Washington
Bridges of various construction span Mount Rainier's major streams and lesser tributaries. One of the most interesting is the Nisqually River suspension Bridge at Longmire, originally built in 1924 of logs and hewn timbers. The bridge was reconstructed of dimensional lumber in 1952 but basically retains its original appearance. It is the only surviving vehicular suspension bridge designed by the National Park Service (NPS). Many of the park bridges appear to be constructed of stone masonry. Actually, these arch bridges are built of concrete and merely faced in stone, characteristic of the NPS Rustic Style. Good examples can be seen at Christine Falls (1928), White River (1929), and Box Canyon (1952). The Fryingpan Creek Bridge (1931) on White River Road is an unusual three-hinged steel web-arch girder designed for this frequently shifting stream. Even smaller bridges and culverts were generally designed to blend with the rugged mountain scenery. Most of the park bridges are constructed on tangents or curves, and are frequently superelevated or banked, offering a smooth transition from road to span. Such designs enable the park roads to sweep gracefully through the spectacular terrain.
