The Green Bridge is the unofficial local name of the Paris Road Bridge carrying Louisiana Highway 47 across the Mississippi River Gulf Outlet between St. Bernard Parish and New Orleans, Louisiana. It is sometimes also called Paris Road Bridge. The name "the Green Bridge" came from it originally being painted green. About 1980 it was repainted brown, and more recently grey, but locals continued referring to it as "the green bridge".
Interstate 510 ends just to the north of the bridge. Both ends of the bridge are in Orleans Parish, Louisiana, but Chalmette, Louisiana is a short distance south of the bridge, which provides the most important road link for St. Bernard Parish, Louisiana, and is one of only four routes into the parish, the others being Judge Perez Drive, the Chalmette Ferry, and the St. Bernard Highway.
