Maryland Route 228

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.

MD 228 did not originally connect Waldorf with Accokeek; instead, the state highway headed west from Waldorf and turned south near the Prince George's – Charles county line, following what is now MD 229 to Pomfret. The state highway was built from Pomfret to Berry in the late 1920s. MD 228 was completed between Berry and Waldorf in the mid-1930s. MD 228 was expanded to a divided highway in Charles County and extended into Prince George's County in the mid-1990s. In 2000, the Prince George's County section of the state highway was reconstructed as a divided highway west to the MD 210 intersection, which was rebuilt as the second continuous-flow intersection in the U.S.
