The route headed to the northwest, following State Street through the northern portion of the village.

At the northern village line, the amount of development along the route decreased substantially as it proceeded through the town of Trenton as Prospect Road.

The route continued on this path for another 0.25 miles (0.40 km) before turning towards the west and paralleling the town line into the village of Remsen.

[3][5] Within Remsen, NY 28B became known as Prospect Street as it headed westward for three blocks through the residential southeastern part of the village.

[8][9] The portion of legislative Route 25 between Barneveld and Prospect was designated as part of NY 287 in the 1930 renumbering of state highways in New York.
