in that capacity for the remainder of its route. Shortly thereafter, the highway crosses over to the west side of the Union Pacific Railroad via an overpass. Continuing northward for another , LA 3 intersects LA 160 at a point near Hughes. LA 160 heads west through Rocky Mount to Cotton Valley in Webster Parish. Now separated from the railroad, LA 3 continues north for another to an intersection with LA 2 (Mary Lee Street) in the town of Plain Dealing, where it gains the local name of Louisiana Street. LA 2 heads west to Hosston and Vivian, connecting to US 71 and LA 1 at those respective points, and east toward US 371 at Sarepta. Several blocks east of this intersection, LA 157 heads northeast to Springhill at the Arkansas state line. north of Plain Dealing, LA 3 intersects LA 537 at a point known as Bolinger. LA 3 continues northward for a final before reaching the Arkansas state line and continuing as Arkansas Highway 29 toward Bradley. History In the original Louisiana Highway system in use between 1921 and 1955, the entire route of the modern LA 3 was part of State Route 10. LA 3 was created in the 1955 Louisiana Highway renumbering, and its route has remained the same apart for two minor shifts at the southern terminus in Bossier City. In the summer of 1966, I-20 was opened in Bossier City from the Red River Bridge at Traffic Street to Barksdale Boulevard (US 71). As part of this construction, the southernmost portion of LA 3 was shifted onto a new connector, in length, known as Benton Spur in order to be aligned with a partial interchange with I-20 at LA 72 (Old Minden Road). The former route along Benton Road then became LA 3 Spur until its deletion from the state highway system in 2010. The second and most recent route change occurred in January 2008 upon completion of the Benton Road Overpass, also in Bossier City. This overpass was constructed on the west side of the existing at-grade crossing of the Kansas City Southern Railway which was formerly a source of traffic congestion on Benton Road. Major intersections Spur route Louisiana Highway 3 Spur (LA 3 Spur) ran a distance of along Benton Road in Bossier City. It provided an alternate connection to LA 72 at the southern terminus of LA 3.
