The Cambie Street Bridge is a six-lane bi-symmetric, precast, varying-depth-post tension-box girder bridge spanning False Creek in Vancouver, British Columbia. The current bridge opened in 1985, but is the third bridge at the same location. Often informally referred to simply as the Cambie Bridge, it is the easternmost of False Creek's fixed crossings; the Burrard and Granville bridges are a little more than a kilometre to the west, and the new Canada Line SkyTrain tunnel is built just west of the Cambie Bridge.
History
The first Cambie Street Bridge, opened in 1891, was built as a simple piled-timber trestle with a trussed timber swing span near the middle. It cost $12,000 (CAD).[1]
Second bridge
The next bridge was a four-lane, medium level steel bridge, 1,247 metres (4,091 ft) long and carrying streetcar tracks. It was completed in 1911 for $740,000, opening to traffic on May 24, 1911.[1] The following year, Canada’s Governor General, the Duke of Connaught, accompanied by the Duchess and their daughter, Princess Patricia, visited Vancouver to officiate at a ceremony renaming the new crossing as the "Connaught Bridge" on September 20, 1912. The name "Connaught" never caught on, and most people continued to call it simply the "Cambie Street Bridge", after the street that runs across it, Cambie Street, named for pioneer Vancouver resident Henry John Cambie.
The navigation span was a steel through-truss swing span which the city would open on four hours' notice. In 1953, it opened 79 times. Even in its later years, it was opened once or twice a week. The trusses of the swing span projected through the bridge deck, dividing the two outer lanes from the two inner lanes. This caused many motor vehicle collisions. In April 1915, the creosoted wood deck caught fire, with the collapse of a 24.4-metre (80 ft) steel side span.

The present bridge
A new, higher, non-opening bridge was built in 1984–85 to replace the 1911 structure. The entire Cambie crossing was closed for nine months, starting November 1984, while the present, six-lane, concrete bridge was merged with the existing approaches. The new bridge cost $52.7 million and was opened on December 8, 1985, after being built to a tight timescale so as to be available for Expo 86 in May 1986. City engineer W.H. Curtis was assisted by E.A. West, Assistant City Engineer, Streets & Structures, who was closely involved in its construction.
The 1985 bridge is of a twin post-tensioned prestressed concrete type in a continuous span. The total structural length is 1,100 metres (3,600 ft), it carries 6 lanes of traffic and a 14-foot (4.3 m) pedestrian walkway. The warm earthen colouring of the concrete was obtained through the addition of volcanic ash from Mount Lassen to the mix.
