Wake and funeral arrangements for a 30-year-old FDNY firefighter who died when he fell off a Brooklyn bridge while helping car crash victims have been set. The wake for Steven Pollard, a probationary firefighter who came from a family of FDNY firefighters, will be held Wednesday from 7 to 9 p.m. and again on Thursday fom 2 to 4 p.m. at Marine Park Funeral Home on Quentin Road in Brooklyn. Pollard will be laid to rest Friday at 11:30 a.m. at Good Shepherd Church on Batchelder Street in Brooklyn. Throngs of firefighters stood at emotional salute Monday as they watched an ambulance carry away Pollard's body who died the night before when he plunged 52 feet to the concrete below the Mill Basin overpass when he responded to an overturned wreck on the westbound Belt Parkway. Pollard went to jump over a 3-foot gap in the road to get from the eastbound to the westbound lanes to help the crash victims but slipped through, officials said.
