A lightweight steel, box-girder bridge with modular concrete deck has been developed for application in many areas. One of PND’s first uses was for the U.S. Army Corps of Engineers, for a bridge traversing the Chena River in Fairbanks. This bridge represented a life cost savings of $2 million. Several major structures near Prudhoe Bay, Alaska, in the Arctic Ocean, and in Anchorage now exist. Several more are planned at remote sites.
