Yosemite floods display on Superintendent’s Bridge

Yosemite valley has become a lake due to flooding many times in history and you can visualize the depth standing on Superintendent’s Bridge, which has a display that you can stand next to, showing the depth of the water during 5 major Yosemite valley floods.

The water overflowed the bridge to these heights as measured from the bridge deck:

Dec. 11, 1937     2.7 feet

Nov. 18, 1950     3.9 feet

Dec. 23, 1955     4.1 feet

To find the Superintendent’s Bridge, take the free Yosemite National Park valley shuttle bus to stop #6. From there, looking across the road at a cross walk near the bus stop, you can see a meandering path leading to a pedestrian bridge over the river (Superintendent’s Bridge).

When you first step up the stairs onto to the bridge from the north, the metal sculpture is on the left hand side.

The section of a shuttle bus map below shows stop #6 at the top center and a dotted red line showing the path to the bridge to the south. The bridge is just below the letter “M” in the words Yosemite Lodge.

You can also find the bridge on your drive into the valley by going directly across Southside Drive from the Chapel and walking a path to the bridge. (Again, see the section of shuttle bus map above and follow the dotted red line from the Chapel going north.

The bridge is in the upper left hand side of this photo taken from the Chapel area:

A third way to find the bridge is to go to free shuttle bus stop #11 (Sentinel Bridge), go through the parking lot to a path / trail some times of the year with large puddles (dotted black line in the mini-map above), roughly parallel to the Merced river, and take a left hand turn to a section of pathway (again, the red dotted line) towards the bridge.

The NPS color photo map below shows the trails to lower Yosemite Falls from shuttle stop #6, the trail to Columbia Rock and on to the top of Upper Yosemite Fall, and the trail thru Cook’s Meadow.

Take a look at the lower section of the figure-8-ish Cook’s Meadow loop, and you can spot where Superintendent’s Bridge crosses the Merced River.
