It carries 10 lanes of traffic with space reserved for a light rail line. The cable-stayed bridge replaced a steel arch bridge that spanned the Fraser River , connecting Coquitlam to Surrey in British Columbia in the Vancouver metro area. After its successor
148-460: A 2-span or 3-span cable-stayed bridge, the loads from the main spans are normally anchored back near the end abutments by stays in the end spans. For more spans, this is not the case and the bridge structure is less stiff overall. This can create difficulties in both the design of the deck and the pylons. Examples of multiple-span structures in which this is the case include Ting Kau Bridge , where additional 'cross-bracing' stays are used to stabilise
222-485: A book by Croatian - Venetian inventor Fausto Veranzio . Many early suspension bridges were cable-stayed construction, including the 1817 footbridge Dryburgh Abbey Bridge , James Dredge 's patented Victoria Bridge, Bath (1836), and the later Albert Bridge (1872) and Brooklyn Bridge (1883). Their designers found that the combination of technologies created a stiffer bridge. John A. Roebling took particular advantage of this to limit deformations due to railway loads in
296-577: A city. Since the 1970s, Burnaby has seen a decline in resource sectors and a subsequent rise of high value-added services and technology sectors. The presence of BCIT and SFU promoted research & development in the area. For example, manufacturing plants near Still Creek closed in the late 1970s, only to reopen few years later as film production studios. The continued expansion of media production in Burnaby contributed to Hollywood North . Burnaby occupies 96.6 square kilometres (37.3 sq mi) and

The Livable Region Coalition urged the Minister of Transportation, Kevin Falcon , to consider rapid transit lines and improved bus routes instead of building the new bridge. The David Suzuki Foundation claimed the plan violated the goals of Metro Vancouver's Livable Region Strategic Plan. The Port Mann / Highway 1 project added another HOV lane along with cycling and pedestrian access. The multi-use pedestrian/bicycle path opened July 1, 2015. A bus service

As Vancouver expanded and became a metropolis, Burnaby was one of the first-tier suburbs of Vancouver, along with North Vancouver and Richmond . During the suburbanization of Burnaby, "Mid-Century Vernacular" homes were built by the hundreds to satisfy demand by new residents. The establishment of British Columbia Institute of Technology (BCIT) in 1960 and Simon Fraser University (SFU) in 1965 helped Burnaby gradually become more urban in character. In 1992, one hundred years after its incorporation, Burnaby officially became

East–west routes linking Burnaby's neighbouring cities to each other include Hastings Street , Barnet Highway ,
3404-572: The design, the columns may be vertical or angled or curved relative to the bridge deck. A side-spar cable-stayed bridge uses a central tower supported only on one side. This design allows the construction of a curved bridge. Far more radical in its structure, the Puente del Alamillo (1992) uses a single cantilever spar on one side of the span, with cables on one side only to support the bridge deck. Unlike other cable-stayed types, this bridge exerts considerable overturning force upon its foundation and
3478-513: The early 20th century as larger gaps were bridged using pure suspension designs, and shorter ones using various systems built of reinforced concrete . It returned to prominence in the later 20th century when the combination of new materials, larger construction machinery, and the need to replace older bridges all lowered the relative price of these designs. Cable-stayed bridges date back to 1595, where designs were found in Machinae Novae ,
3552-826: The first of the modern type, but had little influence on later development. The steel-decked Strömsund Bridge designed by Franz Dischinger (1955) is, therefore, more often cited as the first modern cable-stayed bridge. Other key pioneers included Fabrizio de Miranda , Riccardo Morandi , and Fritz Leonhardt . Early bridges from this period used very few stay cables, as in the Theodor Heuss Bridge (1958). However, this involves substantial erection costs, and more modern structures tend to use many more cables to ensure greater economy. Cable-stayed bridges may appear to be similar to suspension bridges , but they are quite different in principle and construction. In suspension bridges, large main cables (normally two) hang between

By design, all static horizontal forces of the cable-stayed bridge are balanced so that the supporting towers do not tend to tilt or slide and so must only resist horizontal forces from the live loads. The following are key advantages of the cable-stayed form: There are four major classes of rigging on cable-stayed bridges: mono , harp , fan, and star . There are also seven main arrangements for support columns: single , double , portal , A-shaped , H-shaped , inverted Y and M-shaped . The last three are hybrid arrangements that combine two arrangements into one. Depending on
