Built in 1861 by Calvert Vaux and Jacob Wrey Mould, with iron railing by J.B. & W.W. Cornell Iron Works
Stone arch vehicle bridge (sandstone and brick)
Carries East Drive over a park path around 67th Street
Some blocks on the arch are vermiculated with cut designs resembling worm tracks.
This area leading to the Mall was being renovated when I visited in Summer 2007.
