US 165 just inside
Tullos, a small town in northwestern
LaSalle Parish. US 165 connects to
Alexandria on the south and
Monroe on the north. LA 125 briefly proceeds northwest along South Main Street. At Fullerton Road, the highway turns northeast and continues along South Main Street to the town's main junction, an intersection with
US 84. US 84 connects to
Jena, the
parish seat, as well as
Winnfield, the parish seat of neighboring
Winn Parish. LA 125 continues northeast along Main Street, exiting Tullos and intersecting LA 125 Spur, which connects to the parallel US 165. Soon afterward, LA 125 curves to the north briefly before resuming its northeastern course across a bridge over
Chickasaw Creek. The highway then approaches and begins to run parallel to the
Union Pacific Railroad (UP) tracks into the town of
Urania. Here, LA 125 intersects
LA 3259 (East Hardtner Drive), the town's connection to US 165. LA 125 turns northwest, briefly continuing the route of LA 3259 across the UPRR tracks before curving northeast onto Tannehill Drive. The highway continues for through a residential area, at which point it crosses the town limits at Pentecostal Church Road. Shortly afterward, LA 125 passes by a large lumber mill. The posted speed limit is generally between points, reduced to or through town. Average daily traffic volume in 2013 is reported as 850 vehicles for the majority of the route, running from US 84 in Tullos to Standard. The southern and northern ends of the route have lower counts of 550 and 570 vehicles, respectively. LA 125 is an undivided, two-lane highway for its entire length. ==History==
