### Texas to Krotz Springs

LA 7 began at the Texas state line near Deweyville, crossing the Sabine River on a swing bridge. It ran in a straight line along a railroad through the western part of the state, meeting LA 42/US 171 in Ragley and LA 24/US 165 in Kinder before entering Opelousas. LA 7 met LA 5 in Opelousas, which carried US 167, before meeting US 71 and ending in downtown Krotz Springs.

### Lottie to Mississippi

LA 7 was sliced in half with the opening of the Morganza Spillway in the same way that LA 1 was split in half with the opening of the Bonnet Carre Spillway. LA 7 followed the railroad to Livonia, where it met LA 1 and the two were paired to Port Allen. After crossing the Mississippi River in Port Allen, LA 1 turned to the south in Baton Rouge, while LA 7 picked up US 61 and US 190.
US 61 split from LA 7 at a traffic circle, with LA 7 carrying US 190 through the Florida Parishes. US 190 was split from LA 7 in Hammond, where LA 7 met LA 33/US 51. US 190 was paired with US 51 until the 1960s, when US 190 was shifted onto the old LA 7 alignment. LA 7 then passed through Covington and Bogalusa before ending at the Mississippi state line.
