Maryland Route 122 (MD 122) is a state highway in the U.S. state of Maryland. Known as Security Boulevard and Cooks Lane, the state highway runs 2.96 miles (4.76 km) from Rolling Road east to the Baltimore city limit within the western Baltimore County suburb of Woodlawn. MD 122 serves the headquarters of the Social Security Administration and connects the agency with MD 570, I-695, and U.S. Route 40 (US 40). Security Boulevard was constructed in 1960 concurrent with the completion of the Social Security Administration's new headquarters. The six-lane divided highway and the Baltimore County portion of Cooks Lane were transferred from county to state maintenance around 1991.
