Security-Related Traffic Changes on George Washington Bridge Accelerated Structural Cracking

摘要

The Decision implemented by the Port Authority of New York and New Jersey in the aftermath of the terrorist attacks of September 11, 2001, to confine all truck traffic on the George Washington Bridge to the upper deck had the unintended consequence of accelerating the number of cracks occurring in key structural supports for that orthotropic steel deck, explains Robert Kumapley, P.E., M.ASCE, a senior engineer in the Newark, New Jersey, office of the Port Authority, the bridge's owner.
