Historic Aerials confirms this was on the Jefferson Highway, as you can clearly make out the old alignment that continued through Sparrow Lane's intersection with Kateland Road on the 1955 imagery.

Historic Aerials may be my favorite web page :)

Prior to the designation of Route 71 this may have been a part of the Jefferson Highway that preceded 71. A detailed map of the Jefferson Highway might show this. 492 was definitely a part of the Jefferson Highway.

What route did this bridge carry, then? I don't have good copies of the old state route maps. I just guessed US 71 based on the age.

The 1932 Boyce quad shows US 71 using the alignment of 492 to the NE. That alignment may have been created in 1926 when US 71 was established.

Both the topo and google agree that this is called Bayou Rigolette. I don't know where the NBI got Marteau.

Likely another fine example of the original route of US 71.

Very neat. Been riding this area a lot lately but didn't know this existed. Curious as to the history of this bridge. Was this an old alignment of US71 or LA8?
