Maryland Route 162 is a state highway in the U.S. state of Maryland. Known as Aviation Boulevard, the highway runs 2.31 miles (3.72 km) 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 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.
