Louisiana Highway 406 (LA 406) is a state highway in Louisiana that serves Plaquemines and Orleans Parishes. It spans 6.0 miles (9.7 km) and runs in a south to north direction.[1] It is commonly known as Woodland Highway, River Road, and Patterson Drive, and this route serves as a secondary access route for Belle Chasse and Plaquemines Parish.

Route description[edit]

From the southwest, LA 406 begins at an intersection with LA 23 in Belle Chasse. It then runs northward along the east bank of the Gulf Intracoastal Waterway, entering Orleans Parish, reentering Plaquemines Parish, and reentering Orleans Parish for a final time. It intersects LA 407 via a bridge over the Gulf Intracoastal Waterway. LA 406 then passes the English Turn community and becomes River Road/Patterson Drive before ending at an intersection with Stanton Road. River Road continues as a local road until reaching the U.S. Coast Guard Station.

LA 406 is an undivided, two-lane road from LA 23 to south of LA 407. The route then expands to a divided four-lane road at the LA 407 interchange before reverting to an undivided, two-lane road from north of LA 407 to Stanton Road.
