an undivided two-lane highway. In an area known as Gardere, the route crosses LA 327 Spur (Gardere Lane), which leads to the nearby L'Auberge Casino and Hotel on the Mississippi River. Shortly afterward is an intersection with LA 1248 (Bluebonnet Boulevard), connecting to I-10 and the Mall of Louisiana. St. Gabriel and Gonzales Continuing southward, LA 30 simultaneously crosses from unincorporated East Baton Rouge Parish into the Iberville Parish city of St. Gabriel. There is little change in the surroundings, as the city limits encompass scattered rural communities, prison facilities, and industrial plants. Several formerly independent communities, such as Carville and Sunshine are still identified on the directional highway signs. In the center of town, LA 30 passes the local high school and intersects LA 74, which leads through Dutchtown to another connection with the interstate. LA 30 curves southeast away from the CN rail line and proceeds through a small industrial corridor before crossing out of St. Gabriel and into unincorporated Ascension Parish. LA 30 gains a center turning lane and crosses LA 73 near Geismar. The route then curves due east and maintains this trajectory for the rest of its journey. Just beyond LA 3251 (Ashland Road), LA 30 enters the city of Gonzales and passes through a diamond interchange with I-10 at exit 177, connecting with Baton Rouge and New Orleans. The highway becomes a partially developed commercial corridor between I-10 and LA 44 (South Burnside Avenue). It then narrows to two lanes once more and passes through scattered residential development until reaching its terminus at US 61 (Airline Highway) in an area known as Brittany. From this junction, located between Gonzales and Sorrento, LA 431 continues the path of LA 30 and turns northward toward Port Vincent.
