 After the Ingleside segment was constructed with a sand bituminous mix surface in 1946, the highway was proposed to be designated MD 526.However, the following year the Maryland State Roads Commission brought the highway into the state highway system as a segment of MD 305, and additional segments of the Hope–Ingleside highway would be brought into the state highway system as they were completed.The state never did construct additional segments of the Hope–Ingleside road; the roads commission transferred MD 305B from state to county maintenance through a February 19, 1962, memorandum of action.
