Maryland Route 162 (MD 162) is a state highway in the U.S. state of Maryland. Known as Aviation Boulevard, the highway runs from MD 176 near Ferndale north to MD 170 in Linthicum in northern Anne Arundel County. MD 162 forms the eastern portion of the Airport Loop that circumscribes Baltimore/Washington International Thurgood Marshall Airport (BWI Airport) and connects the airport with Interstate 97 (I-97). Most of what is now MD 162 was Maryland Route 167 in the late 1960s and early 1970s; MD 167 previously had been assigned to a different portion of Hammonds Ferry Road in Linthicum from the 1930s to the early 1960s. MD 162 was assigned along the length of MD 167's second route in the late 1980s and immediately relocated at its northern end. The remainder of the highway was expanded to a divided highway in the 1990s. Route description MD 162 begins at an intersection with MD 176 (Dorsey Road) and Stewart Avenue, which forms the southern leg of the intersection, at the southeastern corner of the BWI Airport property south of Ferndale. Eastbound MD 176 provides full access to I-97 and westbound MD 176 forms a continuation of Airport Loop. MD 162 heads north as a five-lane divided highway, with three lanes northbound and two lanes southbound, and follows the eastern boundary of the airport property. The highway's first intersection is with Cromwell Park Drive, which is unsigned MD 162A and has a right-in/right-out interchange with southbound I-97. North of the intersection, MD 162 temporarily expands to six lanes before reducing to four lanes. The highway passes to the west of an industrial park before forming the western edge of a residential subdivision. At the northern end of the subdivision, MD 162 makes a curve to the west, within which it intersects Andover Road, which heads north as MD 762 and south to the historic Benson-Hammond House. The highway passes between a pair of long-term parking lots and crosses Cabin Branch before reaching its northern terminus at MD 170, which heads north through Linthicum as Camp Meade Road toward I-695. Aviation Boulevard and Airport Loop continue west along the other direction of MD 170 toward MD 295 and the main airport entrance. MD 162 is a part of the National Highway System as an intermodal connector for its entire length. History MD 162 follows the path of what was once the southernmost portion
