Local Area Info: Louisiana Highway 1

Louisiana Highway 1 (LA 1) is a state highway in Louisiana. At 431.88 miles (695.04 km), it is the longest numbered highway of any class in Louisiana. It runs diagonally across the state, connecting the oil and gas fields near the island of Grand Isle with the northwest corner of the state, north of Shreveport.

The southern terminus of LA 1 (29°15?37?N 89°57?49?W? / ?29.2603°N 89.9637°W? / 29.2603; -89.9637) is at a dead end in Grand Isle on the south bank of Bayou Rigaud. It heads southwest and west through Grand Isle, turning northwest where it meets LA 3090 (the road to Port Fourchon). At Leeville the road crosses Bayou Lafourche on the Leeville Bridge and begins to parallel the bayou on its west bank, heading through towns such as Golden Meadow, Larose, Lockport, Raceland, Thibodaux, Napoleonville and Paincourtville. At Donaldsonville, where the bayou meets the Mississippi River, LA 1 turns northwest to parallel the river. (Southeast of Donaldsonville, LA 18 and LA 3089/LA 3127 parallel the Mississippi.)

From Donaldsonville to Port Allen, across the Mississippi from Baton Rouge, LA 1 generally parallels the Mississippi River. It takes a relatively straight inland route, bypassing the curves of the river followed by LA 405 and LA 988. At Port Allen, it meets U.S. Highway 190 at the west end of the Huey P. Long Bridge, and turns west with US 190 to past Erwinville. There it turns back north, running along several back channels and oxbows of the Mississippi to New Roads (which is bypassed by LA 3131), and then heading west from New Roads to Morganza with LA 10 (still paralleling the Mississippi). From Morganza to Lettsworth, LA 1 heads northwest near the Mississippi; LA 15 begins in Lettsworth and continues north along the river while LA 1 continues generally northwest towards Alexandria.
