Five teenage boys were arrested for climbing one of the Williamsburg Bridge towers on Wednesday night, police said.

Four 16-year-olds and a 13-year-old were seen by passersby on the Brooklyn-side tower of the bridge around 7 p.m., cops said.

Several witnesses called 911 to report the dangerous stunt and police responded.

The teens removed from the East River crossing without incident by the NYPD’s Emergency Service Unit.

It’s unclear how high up the tower the teens managed to climb.

The five juveniles were all issued summonses for criminal trespass and released to a parent or guardian, cops said.
