The extra lanes added on to the Bronx-Whitestone Bridge in its 60-plus years of use led to a weight problem and undue strain on the aging structure’s suspension cables. Weidlinger Associates designed a new deck-stiffening system, and the original poured concrete steel grid deck will be replaced with a lighter steel orthotropic deck in the next phase of construction.
