Then it proceeds through the portion of Northfield west of the Connecticut River before crossing the Vermont state line, where it continues as VT 142.

Route 142 proceeds north through Bernardston as Mount Hermon Station Road, crossing into the town of Gill and the community of Mount Hermon Station after crossing nearby railroad tracks.

The route parallels the tracks for a short distance, soon turning north and passing Lower Pond.

On the other side of Old Vernon Road, Route 142 passes east of Upper Pond, crossing directly through the center of a nearby quarry in Northfield.

[2] After the quarry, Route 142 turns north again, paralleling the railroad tracks and further east, the Connecticut River.
