Right of way plats for state and federal roads, filed by the State Roads Commission, now the State Highway Administration. The documents show the proposed routes of the roads and contain plat and contract numbers assigned by the highway administration. The records were filed in seven books with post bindings. In four of the volumes the plats are folded to fit within the dimensions of the covers. In the first book and part of the second page numbers were assigned to the plats. Thereafter they are filed on the basis of the date received. This series includes land acquisition plats filed in court cases designed to facilitate the condemnation of land for roads and the payments to land owners. The records require conservation in order to flatten the documents and repair tears. Access available in electronic form derived from the records themselves. Between 1971 and 1990 the road plats were maintained as folded files in series C2227 and between 1990 and 2002 as aperture cards in series C2232. Since October 1, 2002, the records are filed electronically with the Maryland State Archives as (State Road Plats) in series S1742.
