BH Photo #125557
Formally dedicated and opened on August 10, 1940, the bridge served as part of the relocation of US 71 and US 190, allowing traffic to bypass the Baton Rouge-Port Allen ferry at the end of North Street. (US 71 was truncated to Krotz Springs in 1951.)
The roadway is all outboard of the through truss . The railroad runs through the truss structure and the roadways are outboard the truss on cantilevered shelves, one two lane deck on each side of the bridge carrying one-way traffic.
The official name of the bridge was originally the "Huey P. Long-O.K. Allen Bridge", but it is now more commonly called the "Huey P. Long Bridge" and is identified as such on the bridge's signage.
This bridge was very similar to the Huey P. Long Bridge (Jefferson Parish) before the Jefferson Parish structure underwent it circa 2010 widening. Before that the primary difference was that the Jefferson Parish H.P. Long Bridge has two rail tracks. Today the differences are more pronounced.
A 1989 project widened the bridge's roadways by 4 feet.
