The National Park Service is preparing a comprehensive management plan for the Merced River, which flows through the heart of Yosemite National Park. Unfortunately, three historic Rustic Style bridges built in 1928 and 1932 are being considered for removal and face an uncertain future.

In 1864, Yosemite became the nation’s first park devoted to the protection of natural scenery. Today, nearly four million visitors a year journey to its spectacular centerpiece, the seven-mile-long Yosemite Valley, framed by the world-famous Half Dome, El Capitan, and Yosemite Falls. A Merced River Management Plan should protect the river while preserving its iconic and historic bridges.


Protect a collection of historic bridges that span the Merced River in one of America’s most treasured landscapes.

Campaign Goals

      • Work with the National Park Service to protect the historic bridges over the Merced River.
      • Use the bridges of Yosemite Valley to raise awareness about threats facing historic structures, both in parks and along hundreds of waterways classified as Wild and Scenic Rivers.
