The bridge comprises a wide roadway bordered by wide sidewalks. CBA Engineering designed the bridge and oversaw the $15 million project. The superstructure approaches are either concrete or steel I-girders and the main river spans are stiffened steel box girders, comprising a total of 20 spans, 11 piers on land, and 8 in the river. In 1968, the contract for the piers and abutments was awarded to Northern Construction Co and J.W. Stewart ($2,711,000), with work beginning in March 1969. By September, five land piers were complete and the foundations for four more poured. The dredging of fill for the overpass approaches was awarded to Sceptre Dredging ($169,500). as was the dredging of material from the bottom of the river for approach fills, but the shaping of the approaches took a further two months. In September, the placing of the concrete beams began. These light-weight post-tensioned beams were produced on site. In 1971–72, the steelwork for the main superstructure was awarded to Canron Ltd ($2,145,475) and the concrete girders and deck approach spans was awarded to Peter Kiewitt Sons ($1,619,922). By mid-1972, the steelwork for the approaches was erected and for the main spans was progressing. Canron, which prefabricated the 13 structural steel sections that form the box girders of the three main spans, barged these modules from its Vancouver yard to site. Each were up to long and weighed up to 200 tons. That July, the 24-ton floating
Manitowac crane hoisted the first section, which was long, wide, and deep, and weighed 150 tons. After being lifted , it was placed into position on the north centre pier. and the specific
pavement formulation, which had been chosen based on extensive testing, was laid. Whereas the first contract was let in late 1968, the projected completion date moved from fall 1971, to summer 1972, to May 1973, and to June 1973. After four and a half years of construction, Premier
Dave Barrett officially opened the bridge on July 7. The ceremony, which 1,500 people attended, included a parade of vintage vehicles and police cruisers, brass bands, jets flying past, and military personnel parachuting onto the deck from low-flying aircraft. ==Highway bridge operation==
