The first of three enormous support arches for the $1.7-billion Portal North Bridge recently journeyed 30 hours down the Hudson River to the project's jobsite that spans the Hackensack River in New Jersey. The 2.5-mile, fixed-span crossing, which will replace a 114-year-old swing bridge, is a key component of the $33.7-billion Gateway Program that will double rail capacity between Newark, N.J., and New York City.
