MarylandRoute 310 is a state highway in the U.S. state of Maryland. Known as Cayots Corner Road, the highway runs from MD 213 at Cayots east to the Delawarestate line east of St. Augustine in southern Cecil County. MD 310 was built east of St. Augustine by 1921 and west to what was then U.S. Route 213 in the early 1940s. MD 310 was extended west when US 213 was relocated at Cayots in the early 1950s.
Route description
MD 310 begins at an intersection with MD 213 opposite Town Point Road in the hamlet of Cayots. The state highway heads east as a two-lane road past Cayots Corner Road Spur, which heads north to another intersection with MD 213. MD 310 follows the height of land between creeks that flow north into the Elk River and Back Creek and south into the Bohemia River. The highway intersects the southern terminus of MD 342 in the hamlet of St. Augustine. MD 310 reaches its eastern terminus just east of Old Telegraph Road at the Delaware state line. The highway continues east as Churchtown Road, which leads toward the village of Mount Pleasant.
History
Cecil County paved what is now MD 310—which has also been known as St. Augustine Road and Mount Pleasant Road—east of St. Augustine as a macadam road with state aid by 1915. The Maryland State Roads Commission removed an objectionable curve just east of Cayots in 1924. The remainder of the Cayots-St. Augustine section of MD 310 was improved between 1940 and 1942. MD 310's western terminus was originally at the intersection of MD 310 and what is now Cayots Corner Road Spur, where US 213 had a right-angle turn. After US 213 was relocated at Cayots to eliminate the turn in 1951, MD 310 was extended west to its present terminus. The highway was surfaced with bituminous concrete from Cayots to St. Augustine in 1979.
MD 310A was the designation for the Cayots Corner Road Spur, which ran from MD 310 north to MD 213 at Cayots. The highway was originally part of US 213; MD 310A was assigned to the spur after the U.S. Highway was relocated at Cayots in 1951. MD 310A was transferred from state to county maintenance through a December 27, 1979, road transfer agreement.
