in Middle River
north to U.S. Route 40
(US 40) in Rossville
. MD 700 was constructed as a defense access road in 1941 to improve access to the aircraft manufacturing plant of the Glenn L. Martin Company
, one of the predecessor companies of the site's present owner, Lockheed Martin
.
with MD 150 (Eastern Boulevard) in Middle River. The four-lane divided highway continues south as Chesapeake Park Place, which leads into Lockheed Martin's Middle River Complex, a facility of the company's Mission Systems & Sensors business segment. After the southbound direction has a right-in/right-out interchange with Old Eastern Avenue, MD 700 passes under the Amtrak Northeast Corridor and MARC
's Penn Line
. The state highway veers west and intersects Riverton Road and Middle River Road and passes Martin Plaza Shopping Center. MD 700 gently curves to the northwest and crosses Compass Road and Kelso Drive before reaching its northern terminus at a modified trumpet interchange with US 40 (Pulaski Highway).
, then continued east on present-day Baker Avenue to Eastern Avenue just west of the Baker Avenue right-in/right-out
junction with MD 700. Prior to construction of MD 700, the only highway connection to the Glenn L. Martin Company aircraft manufacturing plant in Middle River, which was established in 1929, was MD 150. However, upcoming war conditions required improved connections to military reservations and manufacturers critical to the war effort. A four-lane divided highway with interchanges at US 40 and MD 150 and an underpass of what was then the Pennsylvania Railroad
was included in a list of access roads prepared by the Maryland State Roads Commission
for the United States Department of War
in 1940. MD 700 was constructed in 1941 before federal funding specifically for defense access roads was authorized by the Defense Highway Act of 1941. The state highway, which has only seen minor improvements since 1941, was designated MD 700 by 1946. MD 493 was removed from the state highway system by 1946 and the at-grade railroad crossing was gone by 1949.
