Maryland Route 811 was the designation for Wilson Avenue, which ran from the south town limit of Rising Sun north to MD 273 within Rising Sun in northern Cecil County. The highway was created after the portion of MD 276 between Woodlawn and the town limit of Rising Sun was transferred to county maintenance and MD 276 was placed in its present corridor through a road transfer agreement on May 8, 1958. MD 811 was transferred from state to town maintenance in a road transfer agreement on January 5, 1979.
