Known as Cricket Hill Road, the state highway runs 2.07 miles (3.33 km) from SR 198 at Hudgins north to SR 633 on Gwynn's Island, an island at the mouth of the Piankatank River in northeastern Mathews County.

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] The entire route is in Mathews County.
