The Port Mann Bridge in the Canadian province of British Columbia leads the Trans Canada Highway through the Fraser River and connects the cities of Coquitlam and Surrey near Vancouver. The first building was opened in 1964 steel, anchoring itself in Arch Bridge, which was one of the twenty longest arch bridges in the world. It was replaced by the cable-stayed bridge opened in 2012 and discontinued in 2014. The bridge is named after man at the southern end of the community of Port.
History
The construction of the first Port Mann Bridge began in 1957, the official opening took place on 12 June 1964. The bridge was then the most expensive section of highway, which was realized in Canada. The first, which she passed illegally, was a reporter for the radio station CKNW. The arch bridge was the first four, from 2000, five lanes. The carrying capacity of the bridge was due to the age of the building and increasing traffic to their limits. In its construction it was designed for a population of 800,000. As the population has increased in the area of Vancouver to over two million, it came during up to 14 hours per day traffic jam on the bridge. The provincial government therefore decided to build a new bridge and the old to leave.
The renovation is part of the Port Mann / Highway 1 Improvement Project, abbreviated pMH1 instead, in addition to the renovation of the bridge also includes the expansion of 37 km of the British Columbia Highway 1. For the entire project in 2013 3.3 billion Canadian dollars were budgeted for the construction of the bridge cost 2.5 billion.
The new bridge was originally intended to be implemented as a public-private partnership project, but the province could not agree with the proposed contractor. The construction of the ten-lane cable-stayed bridge was begun in 2009. It was opened on 1 December 2012, but for the time being only eight lanes were put into operation. She was at her opening than the widest bridge in the world .. With the opening of the bridge is also a quick bus connection between Langley and the SkyTrain station in Burnaby has been established. Shortly after the opening of the bridge had to be closed pass because falling ice across the bridge moving cars damaged. To avoid further such incidents, the 154 leading across the roadway cables have been provided with sliding rings on the cables that can be remotely released from the pylon head out in adverse weather conditions. The rings falling rings scrape off ice and snow from the cables before it can come back to as large clusters, which could endanger the traffic being dropped.
The new bridge will be financed by the proceeds from the raised road toll. After the opening, a reduced toll of $ 1.50 per car was raised, which was initially raised in 2014 to $ 3. The toll will be without the traffic stop with license plate cameras charged. The toll will be deducted from a user account or can be paid via various other ways, including mobile payment .. By raising the toll of traffic went on the new bridge by about one -fifth because of traffic to dodge the toll-free Pattullo Bridge.
The two missing lanes of the new bridge can be opened to traffic until 2014, when the old bridge is demolished.
Structures
Bridge from 1964
The old steel arch bridge had a span of 366 meters. Two fields of 110 meters in length joined to the main arch, so that the main bridge was 586 feet long. At this castle in the south of a 525 meter long Vorbrücke and in the north, a 928 -meter-long Vorbrücke, so that the entire structure reached a length of 2093 meters. The demolition of the bridge began in December 2013. In March 2014, the steel superstructures of the bridge spans were already removed. The concrete piers of the bridge spans are upset on sand cushion and disassembled. The main arch is broken down into manageable parts and taken away on the water. The demolition of the old Port Mann Bridge will cost $ 40 Canadian dollars. From the bridge, 18,000 tons of steel and 90,000 tons of recycling are supplied expected.
Bridge of 2012
The zweihüftige cable-stayed bridge is 2020 meters long and are crossing the Fraser River in 42 meters height. With a bridge width of 65 meters and a road width of 50 meters it is one of the widest bridges in the world. The pylons are 163 meters high, the span is 470 meters. She was one of 2014 's top ten cable-stayed bridges with the largest spans in the Western Hemisphere.
The main bridge is 850 meters long and is supplemented by a 350-meter long Vorbrücke in the south and a 820 m long Vorbrücke in the north. For the entire building 25,000 tons hot mix asphalt for road surfacing, 28,000 tons of reinforcing steel and 13,000 tons of structural steel were used. The structure is prepared so that later the trackbed of a light rail can be added below the lanes for road traffic.
