The Chittenden Memorial Bridge is a 120feet concrete and steel arch bridge across the Yellowstone River just upstream from the Upper Yellowstone Falls in Yellowstone National Park. First constructed in 1903 as a Melan arch bridge by park engineer Captain Hiram M. Chittenden of the US Army Corps of Engineers, the bridge was known as Chittenden Bridge from 1912 until 1963, when it was replaced with the current structure. This bridge provides road access from the Grand Loop Road to the secondary road on the south rim of the Grand Canyon of the Yellowstone that allows visitors to see the upper and lower Yellowstone Falls from the south rim.
The first bridge on this site was built in 1903. Chittenden describes the process in his 1915 history of Yellowstone:
By 1912, six years after Chittenden left his duties as park engineer, the bridge had become known as the Chittenden Bridge. In 1961, after a lot of public protest, the National Park Service tore down the original bridge and replaced it with a more modern, wider structure suitable for the type of vehicle traffic the park was experiencing. In an opening ceremony in 1963, the new bridge was christened the Chittenden Memorial Bridge.[2]
