From the northwest, LA 102 begins at an intersection with
U.S. 165 in
Fenton between
Iowa and
Kinder. It proceeds east along a section line road known as Fenton Highway and immediately crosses the
Union Pacific Railroad tracks. It then continues east for two sections to Manuel Road, curves south for two sections to Estes Road, and curves back east for another two sections to an intersection with
LA 99 at Radio Tower Road. From this intersection, LA 99 heads south to
Welsh, and LA 102 turns north, running concurrent with LA 99 along Chaisson Road. After one section, the two highways intersect
LA 3086 at the latter's southern terminus. LA 102 and LA 99 then turn east onto Pine Island Highway and continue for three sections to
Pine Island. The concurrency ends here as LA 99 turns north toward
Lauderdale and LA 102 continues eastward. After two sections, LA 102 intersects
LA 395 (Liberty Cemetery Road) which heads south to
Roanoke. LA 395 turns east and begins a short concurrency with LA 102 that lasts for two sections at which point LA 395 turns north at
Raymond toward
Elton. LA 102 continues east for another two sections and intersects
LA 26 at a point known as
Hathaway. LA 26 also runs to Elton on the north. After one more section, LA 102 turns to the south and parallels LA 26 to
Jennings. Its bannering likewise changes from west–east to north–south. Reaching the northern border of Jennings, LA 102 crosses over, but does not connect with,
Interstate 10 (I-10). Just to the west, LA 26 engages in a full interchange with I-10 at Exit 64. Continuing south into town, LA 102 travels along North Cutting Avenue. At Roberts Avenue, LA 102 intersects
LA 97, and the two highways run concurrent for a short distance to the intersection with
U.S. 90 (East Shankland Avenue). Here, LA 97 reaches its southern terminus, and U.S. 90 continues west parallel with I-10 toward
Lake Charles. LA 102 continues south in a final concurrency with U.S. 90. At East Division Street, the local name changes from North Cutting Avenue to South Cutting Avenue. Shortly thereafter, LA 102 and U.S. 90 intersect South Railroad Avenue at the
BNSF/Union Pacific Railroad crossing. Here
LA 3055 proceeds to the northwest and connects with LA 26 while U.S. 90 turns to the southeast toward
Mermentau. LA 102 then continues south across the railroad tracks. After crossing the southern limit of Jennings, LA 102 intersects
LA 1126. It continues south for four more sections then turns west onto Dugas Road and shortly ends at an intersection with LA 26 about north of
Lake Arthur. ==History==
