Maryland Route 456 (MD 456) is a state highway in the U.S. state of Maryland. Known as Del Rhodes Avenue, the state highway runs 1.20 miles (1.93 km) from U.S. Route 50 (US 50) north to MD 18 within Queenstown. MD 456, which serves as a cut-off between US 50 and US 301 just east of the split of the two highways, is officially separated into two sections, MD 456 and MD 456A, by a superstreet intersection with US 301. The state highway was constructed in the early 1930s as a cut-off between Queenstown and MD 404, then the main east–west highway in western Queen Anne's County. MD 456 was extended south in the late 1940s when US 50 was moved to its present course.
