The E. J. "Lionel" Grizzaffi Bridge is a cantilever bridge in the U.S. state of Louisiana which carries US 90 over the Atchafalaya River between Berwick and Morgan City.[1] Before the 1975 opening, US 90 followed the Long–Allen Bridge.
The bridge will eventually be part of the I-49 extension between Lafayette and New Orleans once the highway is brought up to interstate highway standards.
