Bridge

A bridge is a structure built to span physical obstacles without closing the way underneath such as a body of water, valley, or road, for the purpose of providing passage over the obstacle. There are many different designs that each serve a particular purpose and apply to different situations. Designs of bridges vary depending on the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, the material used to make it, and the funds available to build it.

Etymology

The Oxford English Dictionary traces the origin of the word bridge to an Old English word brycg, of the same meaning. The word can be traced directly back to Proto-Indo-European *bʰrēw-. The word for the card game of the same name has a different origin.

History

The first bridges made by humans were probably spans of cut wooden logs or planks and eventually stones, using a simple support and crossbeam arrangement. Some early Americans used trees or bamboo poles to cross small caverns or wells to get from one place to another. A common form of lashing sticks, logs, and deciduous branches together involved the use of long reeds or other harvested fibers woven together to form a connective rope capable of binding and holding together the materials used in early bridges.

Cambie Bridge

The Cambie Bridge is a six-lane 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. Sometimes referred to as the Cambie Street Bridge, it connects Cambie Street on the south shore of False Creek to both Nelson and Smithe Streets in the downtown peninsula. 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).

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. The following year, Canada’s Governor General, the Prince Arthur, Duke of Connaught and Strathearn, 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 line was first introduced with an Android smartwatch in September 2013 as a spin-off of its Galaxy smartphone and tablet range, and expanded at Mobile World Congress 2014 with a successor, the Tizen-based Gear 2, and the Gear Fit activity tracker.

Cambie Street

Cambie Street is a street in Vancouver, British Columbia, Canada. It is named for Henry John Cambie, chief surveyor of the Canadian Pacific Railway's western division (as is Cambie Road, a major thoroughfare in nearby Richmond).

There are two distinct sections of the street. North of False Creek, the street runs on a northeast-southwest alignment (following the rotated street grid within Downtown Vancouver). As such, the street actually runs perpendicular to the Cambie Bridge, and there is no seamless connection between the two. Instead, Nelson Street carries southbound traffic onto the bridge, and Smithe Street carries northbound traffic away from the bridge. The downtown section of Cambie Street runs from Water Street in Gastown in the north to Pacific Boulevard in Yaletown in the south and is a two-way street for its length.

South of False Creek, the street is a major six-lane arterial road, and runs as a two-way north-south thoroughfare according to the street grid for the rest of Vancouver. This section of the street was originally named Bridge Street, and was first connected to Cambie Street after the first Cambie Bridge opened in 1891; it was renamed Cambie Street after the second Cambie Bridge opened in 1912.
