Before 1 a.m. this morning, a 12-inch water main at 105th Street and Central Park West broke, flooding the West 110th subway station and onto Central Park West. WABC 7 reports, "Several hundred residents of nearby buildings were temporarily without water. Meanwhile, subway service on the A & D lines has resumed with residual delays. M10 bus service was briefly suspended until Central Park West was reopened." While the cause of the break is under investigation, let us guess that it was a combination of crumbling infrastructure and last night's crazy cold temperatures.
