Maryland Route 228 (MD 228) is a state highway in the U.S. state of Maryland. Known as Berry Road, the state highway runs 6.88 miles (11.07 km) from MD 210 in Accokeek east to U.S. Route 301 (US 301) and MD 5 Business in Waldorf. MD 228, which is a four-lane divided highway for its entire length, is a major commuter route between southwestern Prince George's County and northern Charles County. In conjunction with MD 210, the state highway serves as an alternative to US 301 and MD 5 as a route to Washington from Southern Maryland. MD 228 also serves as part of the connection, again via MD 210, between Waldorf and Indian Head Naval Surface Warfare Center.
