Louisiana Highway 30 (LA 30) is a state highway located in southeastern Louisiana. It runs in a northwest to southeast direction from LA 73 in Baton Rouge to the junction of U.S. Highway 61 (US 61) and LA 431 east of Gonzales. The route connects Downtown Baton Rouge with Louisiana State University and travels through the western portion of the campus. Known as Nicholson Drive, this section of LA 30 is a divided four-lane thoroughfare that provides access to many of the school's sports facilities, most notably Tiger Stadium, one of the largest stadiums by capacity in the world. South of the Baton Rouge area, LA 30 cuts across several sharp bends in the Mississippi River. While passing through the rural city of St. Gabriel, its general direction changes from north–south to east–west. The highway then connects a string of chemical plants in the Geismar area to junctions with Interstate 10 (I-10) in Gonzales and US 61 at Brittany. LA 30 was designated in the 1955 Louisiana Highway renumbering, replacing the former State Route 63. The highway initially followed little of its current route, traveling more closely along the Mississippi River southward from Gardere to a different terminus at Darrow. The current alignment, an extension of Baton Rouge's Nicholson Drive, was constructed in stages during the 1960s. Other state highway designations, primarily LA 75, were subsequently extended over portions of the original alignment. Route description Baton Rouge and LSU From the northwest, LA 30 begins at a junction with LA 73 (Government Street) in Downtown Baton Rouge just three blocks from the Mississippi River. The route heads south briefly on the undivided two-lane St. Louis Street. After four blocks, the roadway crosses underneath I-10 at exit 155A and transitions onto the divided four-lane thoroughfare of Nicholson Drive. A ramp connects northbound St. Louis Street with I-10 west to Lafayette, and another leads from I-10 east onto Nicholson Drive in both directions. South of the downtown area, LA 30 cuts through the campus of Louisiana State University and passes closely by Tiger Stadium. Shortly afterward, the highway begins to follow alongside the Canadian National Railway (CN) line while passing Alex Box Stadium/Skip Bertman Field. It then intersects LA 42 (Burbank Drive), which connects to I-10 at the Blue Bayou and Dixie Landin' amusement parks. South of the LSU campus, the surroundings become more rural in character, and LA 30 narrows to
