It travels north along Wittum Road through a light industrial park before heading into a more wooded area paralleling the Union River on its west bank.

About one and a half miles (2.4 km) from here, it meets Mariaville Road, a former alignment of SR 180, and travels along the west shore of Graham Lake passing small houses along the way.

Upon entering the town of Otis, the road passes through a small settlement titled Fletchers Lodge where a general store and an elementary school are located.

SR 180 crossed the Union River just downstream of the dam holding back Graham Lake before it curved to the north and follows what is now its current alignment.

As a temporary measure, the Maine Department of Transportation constructed a single-lane Bailey bridge on top of the existing structure.
