Construction of the bridge was required after the Houma Canal was dug in the 1920s between the Intracoastal Waterway and Bayou Black. It was built by Robinson & Young of Baton Rouge, its design featuring an electrically operated swing span, and opened to traffic on August 5, 1938. It served as part of US 90 until being re-routed onto the Barrow Street extension around 1977, which rendered the bridge obsolete. Claiming its age and unreliability made it an obstruction to marine traffic, the state permanently closed the bridge to all traffic in June 2003 (the swing span remaining in the open position), a move that was controversial with local residents.

At least one local resident has no complaints about the 3197 bridge being held open in perpetuity. . . .

When was this bridge decomissioned and closed to auto traffic?

Why is it classified as "Structurally Deficient?"

Why did it receive a sufficiency rating of 10.1/100?

Where can I go to find all of this information?

Thank you.
