SR 223 begins at an intersection with SR 198 (Buckley Hall Road) at Hudgins. The state highway heads east and curves north through Cricket Hill. North of Cricket Hill, SR 223 crosses Milford Haven, a channel that separates Gwynn's Island from the mainland, and reaches its northern terminus at SR 633 (Old Ferry Road). SR 633 continues northeast through the island's settlements of Grimstead and Gwynn.[1][2]
