Yosemite Valley Bridges, Historic bridges in Yosemite Valley, Mariposa County, United States.

Yosemite Valley Bridges are eight concrete structures faced with local stone that cross the Merced River throughout the valley. They feature different arch designs that connect pathways and allow people to move between different areas of the park.

The eight bridges were built between 1921 and 1933, five of them in 1928. Design work for the seven newer spans was by George D. Whittle of the U.S. Bureau of Public Roads, and Thomas Chalmers Vint urged concrete faced with local stone instead of steel truss or suspension designs. The district was listed on the National Register of Historic Places on November 25, 1977.

The bridges were designed by George D. Whittle of the U.S. Bureau of Public Roads, and concrete faced with local stone was chosen at the urging of Thomas Chalmers Vint instead of steel truss or suspension designs. The uniform rustic character of the eight bridges led to their listing as a historic district on November 25, 1977.

These bridges serve as important connection points for pedestrians and vehicles throughout the park, providing easy access to different viewpoints and hiking trails. They remain accessible year-round, though some sections may close temporarily during heavy snow or high water conditions.

The Ahwahnee Bridge carries Mirror Lake Road across the Merced River, not across Mirror Lake Road itself. Its three arches span 42, 39 and 39 feet, giving a total length of 122 feet, and it was built in 1928 for $59,913.09. Eastbound drivers pass beneath a framed view of Half Dome.
