A boozed-up passenger carjacked a taxi and drove it across the Manhattan Bridge against traffic, slamming into several vehicles before being stopped in Brooklyn, cops said on Tuesday.

Miguel Batiz, 26, hailed a cab at East 21st Street and Second Avenue at around 6 a.m. Sunday and then threatened the driver with a knife, according to authorities.

Batiz got behind the wheel and headed down Second Avenue before driving onto the bridge going in the wrong direction, a criminal complaint says.

He hit one parked car on Second and three other vehicles while crossing the bridge, injuring four people, police said.

Batiz drove two miles into Brookyn before finally being pulled over and surrendering to police, according to court documents.

He allegedly failed a Breathalyzer test at the scene and was charged with driving under the influence, grand larceny, reckless endangerment and leaving the scene of an accident.
