There are eight granite-faced, concrete arch road bridges on the valley floor. Thay were constructed between 1921 and 1933, vith five built in 1928.

The bridges are similar in design, but vary in size and cunfiguration. All bridges are constructed of reinforced concrete in the form of a sent elliptical or three-centercd arch. The concrete is veneered with rough quarried, rock-raced granite which is laid in an uncoursed rubble bond. Thb bridges feature finely cut, rock-faced voussoirs and keystones.

Six bridges span the Merced River, one spans Yosemite Creek and one spans Tenaya Creek.
