 With I-220, the highway helps to carry through traffic between the two disconnected portions of Interstate 49 (I-49), the area's main north–south route.Though the controlled-access highway was officially designated as the Terry Bradshaw Passway in 2003, it is commonly known as the Inner Loop Expressway and is still signed as such from intersecting routes.From the west, LA 3132 begins at a partial cloverleaf interchange with I-20 (exit 11) and I-220 (exits 1B–C) in Shreveport, the largest city in northwestern Louisiana.
