Huey P. Long Bridge (Baton Rouge)
Description
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.

Comments
All I have ever seen of this bridge is in pictures. However, in one of my [KCS] Railroad books, this is the "ruling grade" (steepest) for that sub-division. In other words, the steepest grade in the state of LA for the Kansas City Southern, is a bridge.
There's plenty of good photos of the top side of this bridge (especially thanks to Royce and Bobette Hailey!) but few underneath. So I hope to have done that on a recent visit.
It's a fascinating, gigantic bridge, on which Baton Rouge hopes to route more traffic after the current rehabilitation is complete, due to severe congestion on the I-10 bridge. Compared to I-10, the US 190 HPL bridge is relatively under-utilized. Route LA-1, which connects the west ends of both this bridge and the I-10 bridge, has been widened to 4 lanes. Airline Highway and LA-1 now form a complete loop around the north side of metro Baton Rouge, across this bridge, bypassing the congestion on I-10.
So this latest chapter in the history of the Baton Rouge HPL bridge parallels (again) the history of the New Orleans HPL bridge, which was recently rehabilitated to relieve traffic congestion on the other, newer, Mississippi River bridges.
this bridge is currently being repainted a grey color....the orange paint is being removed. I always understood that the orange paint was chosen because of the bauxite dust from the former Kaiser aluminum plant near the bridge coating the structure and "painting" it orange no matter what the actual color was. But....that could have just been my grandfather (who worked at the old Ethyl chemical plant) pulling my leg.
This bridge has a single rail line. The HPL in New Orleans has dual rail lines. The mention of 1989 may be from when the roadways were widened.
A real workhorse of a bridge! Two train tracks PLUS two vehicular lanes along both sides (4 total lanes for cars) Narrow lanes are less than 9' wide! Very scary with big trucks and cars and trains. I suggest adult diapers for the driver and passengers just keep eyes closed during crossing! See YouTube for videos.
Truss span lengths are 490', 848', 650', 848', and 490'. Engineering News Record had a detailed article on its design and construction.
This bridge was built in 1940. Great site!

This bridge was completed and open to traffic approximately in 1940 not 1989. My father helped construct the substructure of the bridge which is why I was born in Baton Rouge in 1938.

This bridge had a metal railing decorated with flour-de-lis . This railing was replaced around 1990 . I salvaged 100's of the fleur-de-lis from this job and still have one or two !!!
