Huey P. Long Bridge (Baton Rouge)
Posted November 6, 2014, by Benjamin (indyberryfarms [at] gmail [dot] com)

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.

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.
