York Road in Cockeysville reopened today after an early-morning water main break.
Kurt Kocher, a spokesman for the Baltimore City Department of Public Works, said a 12-inch main had broken and that crews were making repairs. He said that one lane of traffic was open in each direction.
Kocher said that the broken main affected "about 20" services in the area and but that many were businesses.
"Our workers have to hand dig the area because of high voltage electric lines and a high pressure gas line." He said water main repairs were completed around 8 p.m. Wednesday.
Baltimore County Police said that at 3:30 a.m. Wednesday a patrol officer came upon a "major water main break" which compromised "the integrity of the southbound lanes" and made traveling northbound "questionable."
Businesses along the affected portion of the road reported that traffic was moving at 9:45 a.m.
Kocher said York Road would continue to operate in one lane in each direction Thursday morning.
