Crossing out of the city limits, LA 12 narrows again to two lanes. It then curves to the northeast to follow the Union Pacific Railroad (UP) tracks for to an area known as Ragley. Along the way, LA 12 crosses into Beauregard Parish once again. The eastern terminus is located at an interchange with US 171 and US 190, specifically at the foot of ramps leading to and from southbound US 171, heading toward Lake Charles. LA 12 briefly widens to a divided four-lane highway to pass through the interchange. Eastbound US 190 continues straight ahead toward Kinder, first connecting to ramps leading to northbound US 171 and westbound US 190, which travel concurrently to DeRidder.
