History

Originally, LA 70 was a much shorter route serving only Assumption Parish and only approximately 17 miles in length. Until the late 1950s, the road went from Pierre Part to Paintcourtville, with its southern terminus being near Belle River in Assumption Parish (four miles south of Pierre Part) and northern terminus at LA 1. In 1958, a swing bridge was built on Belle River, and the road was extended southward to parallel the
