The road between Neponset and Mineral passes through land formerly part of a strip mining operation and now part of the land reclamation process. Portions of the fence lines along the road have blue bird houses affixed to the fence posts, providing homes to some of Bureau County's more colorful feathered friends.

The road also passes the Witness Tree, so named as a reference point, or "witness" for railroad surveyors.

Neponset is the world headquarters for Martin Engineering, the world leader in the problem solving of bulk material handling.

Sitting in south Neponset is the Buswell Mansion. The Buswells were early settlers in Neponset. Col. Nicholas C. Buswell came to Neponset in 1857 and had a hotel and livery business. After the Civil War, he was commissioned to go overseas to buy draft horses for breeding. This was a very successful endeavor. He was a four term County Judge and successful businessman.
