Last night, at least 30 cars were involved in an accident on the Gowanus Expressway—and the culprit seems to be black ice.

The freezing weather has made roads incredibly dangerous, and drivers near 56th Street in Bay Ridge got stuck in the pile-up at 8:20 p.m. WCBS 2 reports, "The pileup happened in the one lane of the Gowanus Extension that is currently under construction, so the cars essentially had nowhere to go, sending them crashing into one another." Nine people suffered minor injuries.

According to WABC 7, "Most drivers were struck in the front and back of their vehicles, caught in the middle of all the other cars." One driver, who was headed to the Rockefeller Christmas Tree, told the Daily News, "I slid for about 20 seconds. I screamed, ‘I can’t stop.' I feel lucky. There was a bus behind us. If it hadn’t been able to stop, we would have been dead."
