091108busbike.jpg50-year-old Jonathan Milstein was struck and killed by a school bus in Park Slope yesterday morning, the second cyclist fatality in Brooklyn in less than a week. (On Saturday, 8-year-old Alexander Toulouse was fatally struck by a mail truck downtown.) The Brooklyn Paper reports that Milstein was riding west on President Street and was trying to make the light at Eighth Avenue, a block from Prospect Park, when the collision occurred. No passengers were on the bus, and no charges filed against the driver, who is reportedly "extremely shaken." Milstein was pronounced DOA at nearby New York Methodist Hospital. A spokesman for Transportation Alternatives told the Brooklyn Eagle that Eighth Avenue is “problematic” because of its proximity to the park and because its one-way traffic and infrequent stop lights seem to encourage speeding.
