This bridge carries 15 lanes of traffic, which makes it (unofficially) the widest bridge (traffic only) in the world.
The design and construction oversight of the Driscoll Bridge was the result of a collaboration between three groups of engineers: the New Jersey Highway Authority staff, the consultants to the Authority for the overall Garden State Parkway project, and the bridge design firm of D.B. Steinman of New York City.
Harold W. Griffin, chief engineer of the New Jersey Highway Authority, carried overall responsibility for the Driscoll Bridge project and was assisted by Harry A. Hartman, supervisor of construction. The firm of Parsons, Brinkerhoff, Hall & McDonald served as general consultants for the Parkway project, and Morris Goodkind served as consulting bridge engineer for the Parkway's bridges. Goodkind was chief bridge engineer at the New Jersey State Highway Department at the time and had been responsible for the design of the Edison Bridge fourteen years earlier.
