Brooklyn Bridge Built in Record Time

This article describes how the new Belt Parkway Bridge in Brooklyn was completed in 261 days--29 days ahead of its fast-track timetable. Innovative precast concrete technology and close cooperation between all involved parties were credited with cutting the construction time. A total of 51 precast, prestressed composite concrete and steel superstructure bridge units were constructed, preassembled and stored at a plant 350 km away from the bridge site until needed. This method of construction decreased the project duration, reduced traffic in and out of the project site by half, minimized the chances of accidents, and eliminated dust, dirt and noise in the surrounding community. The bridge design and construction method should ensure high durability and a long service life.
