Eight people were injured in a multi-car pileup on the Gowanus Expressway.
Police said all the injuries were minor.
The accident happened around 4th Avenue and 57th Street in Sunset Park at about 8:30 p.m. on Tuesday.
More than two dozen vehicles were involved.
There is no word from authorities on what caused the accident.
Temperatures were in the twenties at the time, but the Sanitation Department says the road had been salted about half an hour before.
