The State of Louisiana has a lot of interstate mileage, including some interstate highways that were built in areas not usually accessible by roads. Some of the greatest achievements in building interstate highways include the Interstate 10 bridges through the swamplands and marshes. Other accomplishments include the bridges over the Mississippi River.
And - what was the Larose-Lafitte Tollway all about anyway?

THIS NEXT SECTION IS CURRENTLY UNDER CONSTRUCTION AND PROPOSED!
Interstate 310 - (deleted New Orleans section) - In October 1964, a proposed "Vieux Carre" expressway was officially announced as Interstate 310. This interstate would have gone through the French Quarter of New Orleans. The interstate was never built. For more information click here.
Interstate 610 - under construction in New Orleans
I received the following e-mail from David Backlin (email@example.com) concerning Interstate 49: the last completed section was around Alexandria in 1995 or 1996. This
section is also marked "Bypass US 71". Completed section ran from US71/US167 north to US71/US165 (I think). The section opened previous to that was from LA 3132 to I-20. I-49 North is proposed to run all the way to Kansas City, mostly paralleling US 71. Part of what will become I-49 in Arkansas is currently signed as I-540
(between I-40 and Fayetteville). -- Thanks, David.
The story of how Interstate 10 was built on the TX/LA border, courtesy of Stephen Taylor of Austin, Texas - the bridge at Orange, Texas was designed and built between 1948-52. US 90 at that time veered south after leaving Toomey and then straightened out and entered Orange, TX on a swing bridge built in 1928. Building that two-lane stretch of 90 was a mammoth engineering job; as it went through miles of marsh and swamp to reach the Sabine River after leaving Toomey. Even so, it was only two-lane, and with no way of widening it at all. It was deadly. Both sides were lined with nightclubs, featuring wide-open gambling, prostitution and narcotics, as well as bootleg liquor. Calcasieu Parish was wide open in those years. When WW 2 came, the highway and bridge were taxed even further by the construction of shipyards in Orange; as well as a Naval Base. The swing bridge opened constantly for ships of all sorts, further congesting an already bad situation. The fact that the Highway ran right through downtown Orange made it worse. Orange grew from 9,000 to 70,000 in two years. Something had to be done. A scarcely 10 year old road and bridge were already outdated.
After the war, the respective Highway Departments in both states got together to build a new bridge as part of an overall concept called Super 90. At this same time a similiar style bridge was built over the Neches at Beaumont, for much the same reason. US 90 itself was to be widened and straightened with new safety features added in both states. Planning began in 1948 and construction began in 1950. The site chosen was about 2 1/2 miles north of the existing bridge at Orange. At that point, nothing existed at that site. It was strictly marsh. Bear in mind, this all pre-dated the Interstate Highway System.
Construction was a chore. Since no roads existed, a cement plant was floated on a barge upstream to the site. Workers were carried in and out by boat. All materiel was brought in by barge. The bridge was four-lanes wide; two each direction of course. It was built with a four-foot
mountable median in the middle; this was later replaced with the barrier medians you see today.
I can't speak to the height or style of construction, but I could probably obtain this if you want it.
When the bridge was finished in 52, no roads existed yet on the Texas side but were being built.
