Old Court Road is a state- and county-maintained highway in the U.S. state of Maryland. Including the adjacent road in Howard County known as Woodstock Road, the highway runs 15.4 miles (24.8 km) from Maryland Route 99 (MD 99) near Woodstock east to Joppa Road near Towson. Old Court Road includes two county-maintained sections and two Maryland state highways, Maryland Route 125 (MD 125) and Maryland Route 133 (MD 133). MD 125 has a length of 3.59 miles (5.78 km) between Woodstock and the edge of Randallstown and MD 133 spans 3.31 miles (5.33 km) between MD 129 and MD 25 in Pikesville. Old Court Road connects the western and central Baltimore County communities of Granite, Randallstown, Milford Mill, Pikesville, and Towson. Old Court Road has been a cross-county highway since the colonial era. The highway was fully paved in Baltimore County by the mid-1920s, including the sections of the highway that became MD 125 and MD 133. MD 133 was extended west to MD 140 and MD 125 was extended west to MD 99 in the early 1930s; MD 125's terminus returned to the Patapsco River in the mid-1950s. Old Court Road was relocated at its eastern end in the early 1960s and in Pikesville in the late 1960s, at which time MD 133 assumed its current course.
