Champlain Bridge (Montreal, 2019-present)

The Samuel De Champlain Bridge, colloquially known as the Champlain Bridge, is a cable-stayed bridge design by architect Poul Ove Jensen and built to replace the original Champlain Bridge over the Saint Lawrence River in Quebec, between Nuns' Island in the borough of Verdun in Montreal and the suburban city of Brossard on the South Shore. A second, connected bridge links Nuns' Island to the main Island of Montreal. The bridge is the busiest bridge in the country with more cars flowing into it than any other bridge.[ citation needed ]

Contents

The new span is located just north of the location of the original Champlain Bridge, which began demolition as soon as the new bridge was completed. The new bridge carries eight lanes of automobile traffic of the A-10, A-15, and A-20, with one lane in each direction dedicated for buses. It also includes a multi-use lane for cyclists and pedestrians. The central portion of the bridge deck carries the South Shore branch of the Réseau express métropolitain (REM) automated light metro system. [5] At 60 metres (200 ft) wide, the new Champlain Bridge is the widest cable-stayed bridge in the world that uses two planes of cables. [6]

It is one of the largest infrastructure projects ever built in North America and with an estimated 59 million vehicles a year, one of the busiest crossings on the continent. [7] It is built to last 125 years with the usage of stainless steel and high-performance concrete, [8] and replaces the previous 57-year-old bridge, [9] which had become functionally obsolete and its structure having been degraded by the repeated application of de-icing salt.

Specifications

The Champlain bridge is a 3.4-kilometre (2.1 mi) crossing. It includes an asymmetric cable-stayed bridge with a 240-metre (790 ft) main span, a 168-metre-high (551 ft) concrete tower, and stay cables in a harp arrangement. The asymmetrical back span is 124 metres (407 ft). The 2,044-metre (6,706 ft) west approach structure has 26 spans that are typically 80.4 metres (264 ft).The east approach is 780 metres (2,560 ft) long and includes a 109-metre (358 ft) span over Route 132. [6]

The bridge was built as part of a larger $4 billion project that included:

The design of the Champlain Bridge addressed seismic activity, soil liquefaction, light-rail transit loading, ship collision, and ice loading. The bridge is configured with three separate decks, one for each direction of vehicular traffic and a third in the center for the Réseau express métropolitain rail corridor. The northbound deck is wider to include a multi-use corridor for cyclists and pedestrians, requiring the cable-stay bridge to be asymmetric in the transverse direction as well as longitudinal. The main tower is shaped like a tuning fork and is supported by twenty-one 1.2-metre (3.9 ft) drilled piles. The decks are supported in the approach spans by W-shaped piers. [6]

Construction history

In September 2007, faced with rising costs for the maintenance of the Champlain Bridge (commissioned in 1962), then Canadian Minister of Transport Lawrence Cannon confirmed that his department was seriously considering the construction of a replacement structure. In August 2008, Transport Canada announced that it was exploring different scenarios for a new bridge. In October 2011, then Minister of Transport Denis Lebel officially announced that construction on the new bridge would begin within 10 years.

In November 2014, then Minister of Transport Lisa Raitt announced that she was abandoning the idea of naming the new bridge in honor of Maurice Richard after consulting the family of the former ice hockey champion. Prior to the 2015 Canadian federal election, the 28th Canadian Ministry planned on imposing a $2-$4 toll on the new bridge, however, this plan was abandoned following the election of the 29th Canadian Ministry.

In April 2015, the federal government selected the JV consortium: Signature on the St. Lawrence Group to build the new bridge. The consortium mainly includes: SNC-Lavalin, the Spanish ACS Infrastructure, and Dragados Canada. T.Y. Lin International is serving as the Lead Designer. [11]

Construction on the new bridge officially began on June 16, 2015. On December 19, 2018, Minister of Infrastructure and Communities François-Philippe Champagne announced that the official name of the new bridge will be the Samuel-de-Champlain Bridge. [12] The bridge opened to northbound/westbound traffic on June 24, 2019 (St-Jean-Baptiste Day), with the official opening ceremony being held on June 28, 2019, and southbound/eastbound traffic opening on 1 July 2019 (Canada Day). The multi-purpose runway was opened in November 2019 followed by the REM train tracks on July 31, 2023. [13] [14]

Construction method

View from the westbound roadway

In order to meet the 42-month construction deadline, many steel and concrete bridge elements were prefabricated, with a portion of the work taking place on temporary piers. Three jetties were built: one on the east from Brossard, one on the west from Nuns' Island, and one from the center, adjacent to a dike along the Saint Lawrence Seaway.

<span class="mw-page-title-main">Cable-stayed bridge</span> Type of bridge with cables directly from towers

A cable-stayed bridge has one or more towers, from which cables support the bridge deck. A distinctive feature are the cables or stays, which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines. This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from the main cable, anchored at both ends of the bridge and running between the towers. The cable-stayed bridge is optimal for spans longer than cantilever bridges and shorter than suspension bridges. This is the range within which cantilever bridges would rapidly grow heavier, and suspension bridge cabling would be more costly.

<span class="mw-page-title-main">Extradosed bridge</span>

An extradosed bridge employs a structure that combines the main elements of both a prestressed box girder bridge and a cable-stayed bridge. The name comes from the word extrados, the exterior or upper curve of an arch, and refers to how the "stay cables" on an extradosed bridge are not considered as such in the design, but are instead treated as external prestressing tendons deviating upward from the deck. In this concept, they remain part of the main bridge superstructure.

Garratt Road Bridge consists of two adjacent bridges over the Swan River, linking the suburbs of Bayswater and Ascot in Perth, Western Australia. The upstream bridge was built in 1935, while the matching downstream bridge was built in 1972. The site was significant prior to the construction of Garratt Road Bridge – it featured in Aboriginal mythology, and was in the near vicinity of 1880s bridges for pedestrians and trains. From that time there were various proposal to provide a vehicular crossing between Bayswater and Bassendean. Interest peaked in 1928, but plans were delayed due to the Great Depression. The first bridge, designed by Main Roads Chief Engineer Ernest Godfrey, was constructed in 1934–35. It allowed two lanes of traffic to cross the Swan River, alongside pedestrians on an adjacent footbridge.
