The Vine Street Expressway reopened at about 9 a.m. Sunday after a water main break coated the major thoroughfare in ice, leading to a shutdown.
The expressway's westbound lanes reopened shortly before 9 a.m. and the eastbound lanes just after that.
The break appears to be in a 8-inch main under the 17th Street overpass.
Water also flowed into manholes, where it turned into dramatic clouds of steam.
