Alvord Bridge, in the eastern end of Golden Gate Park, was built in 1889 by the pioneering engineer Ernest L.

The feature is not a local landmark but is a contributing feature in the GGP National Register of Historic Places. The bridge and its four curving abutment walls are constructed of formed concrete. The abutment walls are cracked and displaced by lateral pressure from soil and tree roots.
