About: Maryland Route 152

Maryland Route 152 (MD 152) is a state highway in the US state of Maryland. The state highway runs 17.34 miles (27.91 km) from an entrance to Aberdeen Proving Ground in Edgewood north to MD 146 near Taylor. MD 152 parallels the western edge of Harford County, connecting the communities of Joppatowne and Fallston with Interstate 95 (I-95), U.S. Route 40 (US 40), and US 1. The state highway north of Joppa was mostly built in the late 1920s and early 1930s. MD 152 south of Joppa was built around 1940; shortly thereafter, the highway was reconstructed as a wartime access project. The state highway originally had only a partial interchange with I-95; it was expanded to full interchange in the mid 1990s concurrent with the expansion of the highway to a four-lane divided highway through Joppa.
