The 5.2-mile improvement project on State Route 76 included widening a two-lane road to a divided four-lane highway and updating bridges over the San Luis Rey River. The project team worked around Native American protected sites in a sensitive river floodplain. “The team was six months early in the delivery despite working in a pretty highly environmental area,” a judge said. The project restored 1,600 acres of habitat, and the team scheduled vegetation clearing and pile-driving around habitat breeding seasons. The project also built a bridge over culverts supplying water to the San Diego area. To protect the culverts, girders for the new bridge were transferred in mid-air using two cranes, each positioned at different bridge abutments.
