NEW YORK, N.Y. : The Greenwich Village air was sweet with the smell of burning tar, which mingled with souvlaki and honey-roasted peanuts in an olfactory mosaic. Staccato bursts of jackhammer noise, accompanied by equally rapid-fire cursing from road workers, served as percussion for the usual symphony of ambulance sirens and car horns. Weak sunlight filtered gamely through the smog; most blocks had at least one sidewalk passable; in short, it was the perfect day for a stroll down to Cooper Union to talk about the infrastructure.
The Triborough Bridge Project is a three-branched waterway crossing that connects Manhattan, the Bronx, and Queens at a junction of the East River and the Harlem River in New York City. The complex structure includes a suspension bridge from Wards Island to Queens, a vertical lift span from Randall's Island to Manhattan, a fixed span (designed to be convertible to a lift span) across the Bronx Kills, viaducts, and an innovative three-legged roadway interchange.
