Governor Alfred E. Driscoll Bridge, NJ, is a twin cantilever truss bridge that carries Interstate 295 (I-295) over the Delaware River. The south end of the bridge is in Burlington, Mercer County, New Jersey; and it crosses into Hamilton Township, Mercer County, New Jersey. From there it continues over the west channel of the Delaware River to connect with the Trenton Freeway (US 1/US 13) in the city of Trenton, Mercer County, New Jersey. It was named after Governor Alfred E. Driscoll when he died in office in 1964.
Construction of the original twin cantilever truss spans began in August 1963. Each span was to have consisted of the main span, along with approach viaducts that were supported by cast-in-place concrete piers. The construction contract for the first viaduct was awarded to Vendome Construction Company on June 25, 1964, at a bid of $6,000,000 (1964 USD). The roadway was designed to handle a capacity of 75,000 vehicles per day. Construction was halted for six months in December 1965 after completion of the first span when an engineering study found that the south cantilever pier would require additional work to avoid settlement and failure. A design change order to include massive rocker bearings was issued on January 27, 1966 at a cost of $2.4 million (1966 USD). The south span was completed in September 1968, with work on the north span continuing until its completion in December 1969.
The bridge originally carried Interstate 95 over the Delaware River before it was re-designated as part of I-295 in 1973. A construction project completed in 1997 by the New Jersey Department of Transportation (NJDOT) modified the bridge’s approach roadways, built new storm drainage systems, and created a landscaped median in Hamilton Township, Mercer County.
Nowadays, Governor Alfred E. Driscoll Bridge carries eight lanes of Interstate 295, in a north-south direction. The bridge has a total length of 4,392.3 ft., with the main cantilever span that is long and another shorter span between the north end piers. On its western (Hamilton Township) side it has approach viaducts, each with five lanes and a sidewalk. The bridge’s eastern (Trenton) side also has an approach viaduct, but with four lanes and no sidewalks.
Governor Alfred E. Driscoll Bridge is the widest bridge in the world! In fact, Governor Alfred E. Driscoll Bridge is actually two bridges counted as one! The twin spans are held side-by-side and carry I 295 from near Burlington, NJ to Trenton, NJ.
