About: Maryland Route 146

Maryland Route 146 (MD 146) is a state highway in the U.S. state of Maryland. The state highway runs 16.81 miles (27.05 km) from MD 45 in Towson north to MD 23 near Jarrettsville. MD 146 connects Towson with Loch Raven Reservoir, an impoundment of Gunpowder Falls. The state highway also serves the northern Baltimore County community of Jacksonville and Jarrettsville in western Harford County. MD 146 was constructed as two different state highways on either side of Loch Raven Reservoir. The section of the state highway in Towson was built in the 1910s and the portion through Jacksonville to Jarrettsville was constructed in the late 1920s and early 1930s. The gap in MD 146 through Loch Raven Reservoir was filled in two steps of maintenance swaps in the early 1960s and late 1970s.
