. LA 300 heads northward from the fishing communities of Delacroix and Reggio. The winding and notoriously dangerous road meets LA 46 north of Reggio and turns westward. This section of LA 300 parallels the newer four-lane highway carrying LA 46 to the north. LA 300 proceeds for about farther to its terminus at Sebastopol. It is an undivided two-lane highway for its entire length. In 1997, the Louisiana DOTD controversially placed two barriers in the road, effectively dividing it into three dead end segments, in an effort to encourage drivers to use the then-newly constructed LA 46, the Judge Perez Extension, which was 4 lanes and divided, saving Bayou Road for more local traffic, as the road has no shoulder at points.

This route continued southward by ferry across Bayou Villars and followed the present LA 3257 to Bayou Rigolettes opposite the small community of Lafitte. In 1948, the ferry service was replaced by the present bridge across Bayou Barataria on nearby LA 302 (former State Route C-2060).
