Anyone who has recently driven on I-76 through Philadelphia has probably noticed the "waterfall" dropping from an overpass near 30th Street Station.  Even on the sunniest of days, your car can get drenched when you pass through this section of the Schuylkill Expressway.

NBC10 asked PennDOT about this situation and found out that "water is needed to cure concrete pavement being poured as part of the Schuylkill Avenue Viaduct replacement process."

PennDOT spokesman, Brad Rudolph, told NBC10, "When concrete pavement is poured, there is a 14-day curing period where the fresh concrete is covered in burlap and perforated drip hoses are positioned atop the burlap to provide a steady supply of water to keep the burlap wet during the cure.”

The dripping is expected to last quite a bit longer. In fact, you'll have to wait until the dead of winter for it to stop. They say it will continue until the temperature is cold enough to freeze the water.
