I-49 was extended north into Shreveport to a temporary terminus at LA 3132 around 1991. LA 3132 served as the main connector to eastbound I-20 until the two interstates were directly connected in December 1995. By the mid-1990s, as plans for the Inner Loop Expressway changed, the portion of LA 3132 connecting to LA 511 at the Jimmie Davis Bridge became part of LA 526. LA 3132 was then extended on its east end straight across LA 526 to a new terminus at LA 523. This last project was completed in September 2007.
