They were built in 1930-1931.","why_significant":"The bridges are cited as locally significant in architecture and landscape architecture for their design and workmanship. They were designed by National Park Service landscape architect John Wosky to blend with their natural settings, using ideas from Westchester County, New York parkway bridges. They are described as among the last of the large, hand-crafted highway structures.","narrative":"Two stone-faced highway bridges carry the Generals' Highway across the Marble Fork of the Kaweah River and Clover Creek in Sequoia National Park. Built in 1930-1931, each has a reinforced concrete barrel arch hidden behind massive uncoursed masonry. The Marble Fork span measures 45 feet and the Clover Creek span 90 feet, and each carries a 25-foot roadway. John Wosky, a National Park Service landscape architect, designed them after observing bridges with concrete cores and rustic stone exteriors in Westchester County, New York. The goal was to keep road structures from intruding on the landscape. W. A. Bechtel Company won the contract but underestimated costs, and subcontractor C. D. DeVelbiss finished the work in October 1931 using Finnish stone cutters who shaped hard granite into precise blocks. The native stone was chosen to match each setting. The bridges are recognized locally for their architecture, landscape design and craftsmanship, and both remain unaltered and in excellent condition.","period_of_significance":"1930-1931","architect_builder":"National Park Service (designer John Wosky); built by W.
