233.9 US 190 And Railroad Bridge (Old Bridge)
The “Old Bridge” was originally opened in 1940 and officially named the Huey P. Long Bridge. Legend has it, that famous (or infamous, depending on your point of view) Louisiana Governor Huey P. Long had this bridge built to a height that would prevent large ship traffic from being able to navigate any further upriver, forcing them to utilize the port of Baton Rouge and keeping a monopoly on deepwater ship traffic in Louisiana
