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 Atchafalaya River through Lower St. Martin and upper St. Mary Parish to reach Morgan City.
The northern extension of LA 70 from Paincourtville/Plattenville to Sorrento/I-10 occurred in 1977. The road was extended from LA 1, crossing Bayou Lafourche, to LA 3089. LA 70 then assumed most of LA 3089's original routing, crossing the Sunshine Bridge to connect to LA 22 near I-10 in Sorrento.
