[edit] Route Description
LA 18 begins as an undivided, two lane road in downtown Donaldsonville as Bayou Road, which runs parallel to the Mississippi River. It intersects with the Sunshine Bridge (LA 70) east of Donaldsonville, the Veterans Memorial Bridge (LA 3213) south of Gramercy, and Interstate 310 near Luling as it continues downriver. At Bridge City, LA 18 shortly merges with U.S. Highway 90 but continues its eastward span while U.S. 90 crosses the Mississippi River via the Huey P. Long Bridge. When LA 18 enters Westwego, LA 18 becomes 4th Street but still continues alongside the river. In Gretna, LA 18 turns south, away from the river, onto Lafayette Street and ends at the intersection of Lafayette St. and the Westbank Expressway.
