A state police report said the two jumps were "unprecedented" on the bridge, which links Rockland and Westchester counties. The state Thruway Authority says more than 25 people have made fatal jumps from the Tappan Zee Bridge in the last decade.
Witnesses saw the first man jump at about 1:40 p.m. The 55-year-old man's name was not made public, but he was from Montvale, New Jersey.
As his body was being taken ashore, witnesses reported the second man's jump. Police identified the second jumper only as a 27-year-old man from Ossining.
