The two highways exit the town as Dundas Road, which curves to the south and crosses over an abandoned railroad grade.

The state highway crosses over the former rail line again, then turns right at SR 645 (Jonesboro Road) to remain on Dundas Road, which parallels the abandoned rail line to the hamlet of Dundas.

SR 137 turns south at the northern segment of SR 603 (Potts Spring Road), intersects the former rail line, and turns east again at the southern segment of SR 603 (Mill Pond Road).

East of Dundas, the state highway crosses the Lunenburg–Brunswick county line.

SR 137 continues on Danieltown Road to its eastern terminus at SR 46 (Christanna Highway) at the hamlet of Danieltown.
