The part south of U.S. Highway 90 near Raceland is Corridor 44, a National Highway System High Priority Corridor. From Alexandria to Shreveport, the LA 1 corridor was used for Interstate 49.

Between New Roads, Louisiana, and the interchange with I-49 at Alexandria, Louisiana, LA 10 forms part of the [http://www.zacharytaylorparkway.com/Parkway/index.php Zachary Taylor Parkway.]

Route description

The southern terminus of LA 1 (coord|29.2603|N|89.9637|W) 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 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.

LA 1 heads inland through such towns as Moreauville and Marksville to Alexandria, where it meets the Pineville Expressway (U.S. Highway 165/LA 28). LA 1 turns southwest along its frontage roads - Fulton Street and Casson Street - along with LA 28 Business and U.S. Highway 167 Business to its end at Interstate 49, and continues southwest on Mason Street and northwest on Bolton Avenue.

From Alexandria to Shreveport, LA 1 generally parallels Interstate 49, including a bypass around Natchitoches. Louisiana Highway 1 Business runs through downtown Natchitoches before rejoining the original highway just northwest of the city limits. It passes through Shreveport on Youree Drive, Spring Street and Market Street, running concurrently with U.S. Highway 71 from Interstate 20 downtown to a split north of downtown. From Shreveport to the border with Texas, where LA 1 becomes State Highway 77, LA 1 passes through towns such as Oil City, Vivian and Rodessa.
