About: Maryland Route 145

Maryland Route 145 (MD 145) is a state highway in the U.S. state of Maryland. The state highway runs 10.34 miles (16.64 km) from MD 45 in Cockeysville east to MD 165 near Baldwin. MD 145 connects the north-central and eastern portions of Baltimore County via Jacksonville. The first section of the highway was built from Loch Raven Reservoir to Jacksonville in the early 1910s. The remainder of MD 145 east to Baldwin was completed in the mid-1920s. The state highway was extended west to Cockeysville in the early 1980s in a maintenance swap. When MD 145's bridge over Loch Raven Reservoir was replaced in 2000, the old bridge from 1922 was preserved.
