Louisiana Highway 23 (LA 23) is a north–south state highway in Louisiana that serves Plaquemines and Jefferson Parishes. It spans 74.0 miles (119.1 km) in roughly a southeast to northwest direction. It is known locally as Belle Chasse Highway, Lafayette Street, the West Bank Expressway, and Franklin Avenue.
LA 23 connects Gretna and Venice. Between Belle Chasse and Venice, the highway serves as the main road along the west bank of the Mississippi River. In Belle Chasse, the highway crosses the Gulf Intracoastal Waterway via two antiquated crossings: southbound traffic uses the 1955-vintage Belle Chasse Tunnel, a narrow crossing that does not allow passing; northbound traffic uses the 1967-vintage Judge Perez Bridge, a vertical-lift bridge. LA 23 runs through the small rural towns of Jesuit Bend, Naomi, Myrtle Grove, West Pointe à la Hache, Port Sulphur, Nairn, Empire, Buras, Triumph, and Boothville. With the exception of the portion running through Port Sulphur, the entire highway is four lanes (although it is not controlled-access).
