After , LA 109 curves to the northeast and travels another to a point known as Fields. Here LA 109 intersects LA 389, which connects to US 190 in Merryville on the northwest and LA 12 in DeQuincy on the southeast. From this intersection, LA 109 and LA 389 turn to the east, engaging in a brief wrong-way concurrency (though directional banners are not used here) before LA 109 turns off again to the northeast. During its final , LA 109 passes through a point known as Mystic and reaches its northern terminus at an intersection with LA 27 at Juanita. LA 27 heads through Singer to DeRidder on the north and through DeQuincy to Lake Charles on the south.
