In 1948, Kent County requested that the
Maryland State Roads Commission make improvement of Flatland Road its highest priority project in the county during the post–
World War II road building effort. The highway from MD 20 to Hanesville Road was constructed in two sections. The first section was built as a gravel road in 1949, and the gravel road was improved with bituminous stabilization the following year. MD 514 was extended to Hanesville Road as a gravel road in 1954. The highway was resurfaced with bituminous concrete in 1970. Melitota Road was transferred from county to state maintenance through a December 1, 1987, road transfer agreement, and the road was confirmed as an extension of MD 514 in July 1988. ==Junction list==
