Bennett Street continues west as SR 673 toward Justisville.

SR 176 heads southeast as a two-lane undivided road and has a grade crossing of an inactive railroad line immediately to the east of SR 316, passing to the south of the Eastern Shore Railway Museum before exiting the town.

The state highway follows Parksley Road southeast from the town limit to the route's eastern terminus at US 13 (Lankford Highway) in the hamlet of Centerville.
