Louisiana Highway 1 (LA 1) is the longest state highway in Louisiana, as well as the longest highway of any type in Louisiana. It runs approximately 431.88 miles (695.04 km) in a southeast-to-northwest direction from a dead end in Grand Isle to the Texas state line northwest of Rodessa.
The route submitted runs from northwest to southeast and will start at the Three Corners Marker just northwest of Rodessa and will end at the dead end in Grand Isle. The route also bypasses the Gateway to the Gulf Expressway and will follow the Old Hwy 1 portion of the route in the Leesville area. Due to a portion of this area no longer having a bridge; a boat, kayak, pirogue, or some means of transportation will be needed to cross the short waterway section.
LA 1 will take you through the heart and many different rich cultures of Louisiana. From the flashy riverboat casinos of Shreveport, to Louisianas oldest permanent settlement of Natchitoches, through the red dirt hills and longleaf pines of Kisatchie National Forest, near the capital of Baton Rouge, into the cajun country of Thibodaux, and along the gulf coast region of Grand Isle.
