I-76 has reopened in both directions after up to 6 to 8 inches of rain from the remnants of Ida fell across parts of the Philadelphia region Wednesday, leading to widespread flooding that closed some of the city's major roadways as the water rushed from the Schuylkill River.

Both I-676 and Kelly Drive remain closed.
Earlier in the day, water from the Schuylkill River flowed onto the Vine Street Expressway, turning it into a river of water that cut Center City in half from 22nd Street to Broad Street.
Cars and trucks were going through the flooded Schuylkill Expressway near 30th Street during the Thursday morning commute before PennDOT shut down the roadway at 30th Street and ramps between City Avenue and the South Street Bridge around 6:40 a.m. Floodwater swamped the roadway under 30th Street through much of the morning.
