Picking up a station
Roads & Bridges

Peter Pomeranz, P.E., and Joseph Faro, P.E.
The Kosciuszko Bridge, a steel and concrete structure approximately 4,000 ft in length, connects the boroughs of Queens and Brooklyn. The NYSDOT awarded a contract to Ahern Painting Contractors Inc. to clean, paint and replace steel on the bridge. About 10 months after work began, the painters complained about electrical shocks whenever they touched the steel on the bridge while standing on a man lift.
