Route description

LA 631 was the original route of US 90 before its current neighboring four-lane alignment was constructed. Its entire length parallels US 90 and the nearby railroad line. From the west, it begins at an intersection with US 90 in extreme eastern Lafourche Parish, just before Bayou Des Allemands. Crossing the bayou, it heads into St. Charles Parish and through the main part of Des Allemands. There it crosses the LA 631 Spur, LA 632, and LA 635. Just before Paradis, it meets LA 306. It ends a few miles further to the northeast in Boutte at an intersection with LA 52 just after crossing under (but not connecting to) Interstate 310/LA 3127.

LA 631 is an undivided, two lane highway for its entire length.
