Route description
From the southeast, LA 30 begins at an intersection with US 61 and LA 431 halfway between Gonzales and Sorrento. LA 30 then runs due west, intersecting LA 44 and I-10 in Gonzales. It passes the Tanger Factory Mall at its intersection with Interstate 10. LA 30 then turns northwestward and crosses LA 73. While passing various chemical enterprises, the highway enters Iberville Parish before crossing LA 74 at St. Gabriel. The highway then enters East Baton Rouge Parish and eventually the city of Baton Rouge proper, at which time it becomes Nicholson Drive. After passing LA 42 and LSU, it widens to four lanes and turns northward. In its final stretch, it moves into downtown Baton Rouge and crosses Interstate 10 one last time and ends at LA 73 (Government Street).
