The Port Mann Bridge in the Canadian province of British Columbia leads the Trans Canada Highway over the Fraser River and connects the cities of Coquitlam and Surrey near Vancouver . The first structure was the steel arched bridge that was opened in 1964 and was one of the twenty longest arched bridges in the world. It was replaced by the cable-stayed bridge opened in 2012 and demolished by October 2015. The bridge is named after the community of Port Mann at the southern end.
history
Construction of the first Port Mann Bridge began in 1957 and the official opening took place on June 12, 1964. At the time, the bridge was the most expensive section of the freeway to be built in Canada. The first to pass it illegally was a reporter for the radio station CKNW. The arched bridge initially had four lanes and from 2000 five lanes. The load-bearing capacity of the bridge reached its limits due to the age of the structure and the increasing traffic. When it was built, it was designed for a population of 800,000. As the population in the Vancouver area rose to over two million, traffic jams on the bridge were up to 14 hours a day. The provincial government therefore decided to build a new bridge and demolish the old one.
The renewal is taking place as part of the Port Mann / Highway 1 Improvement Project , abbreviated PMH1 , which includes the renewal of the bridge and the expansion of 37 km of British Columbia Highway 1 . In 2013, 3.3 billion Canadian dollars were budgeted for the entire project, while the construction of the bridge cost 2.5 billion.
The new bridge was originally intended to be a public-private partnership project , but the province was unable to come to an agreement with the proposed contractor. The construction of the ten-lane cable-stayed bridge began in 2009. It was opened on December 1, 2012, although only eight lanes were put into operation for the time being. When it opened, it was considered the widest bridge in the world. With the opening of the bridge, an express bus connection was also established between Langley and the SkyTrain station in Burnaby . Shortly after opening, the bridge had to be temporarily closed because falling ice damaged cars driving over the bridge. To avoid further such incidents, the 154 cables running over the carriageway were provided with rings that slide on the cables, which can be released remotely from the pylon head in unfavorable weather conditions. The falling rings strip ice and snow from the cables before they can accumulate so large that if they fall they can endanger traffic.
The new bridge was to be financed by the revenue from the road toll. After the opening, a reduced toll of $ 1.50 per car was levied, which was raised to $ 3.00 in early 2014. The toll is collected using license plate cameras without stopping traffic. The toll was debited from a user account or could be paid in various other ways, including cell phone payments. With the increase in the toll, traffic on the new bridge fell by around a fifth, because some of the traffic has switched to the toll-free Pattullo Bridge . Due to changed political framework conditions, the toll obligation was abolished at the end of August 31, 2017.
The two missing lanes of the new bridge could only be opened to traffic in 2014 after the old bridge had been removed. On September 17, 2015, the construction work, including all ancillary work on access ramps, etc., was declared completed.
Buildings
Bridge from 1964
The old steel arch bridge had a span of 366 meters. The main arch was joined by two fields of 110 meters in length, so that the main bridge was 586 meters long. This was followed by a 525 meter long fore bridge in the south and a 928 meter long fore bridge in the north, 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 fore bridges were removed. The concrete pillars of the approach bridges were tipped over on sand cushions and crushed with jackhammers. The main bow was broken down into manageable parts and carried away on the water. The demolition was completed by October 2015. The cost of demolishing the old Port Mann Bridge was estimated at 40 million Canadian dollars. When the bridge was demolished, around 18,000 tons of steel and 90,000 tons of concrete were recycled.
Bridge from 2012
The two-hip cable-stayed bridge is 2020 meters long and crosses the Fraser River at a height of 42 meters. With a bridge width of 65 meters and a roadway 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. In 2014 it was one of the 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 fore bridge in the south and an 820 meter long fore bridge in the north. For the entire structure, 25,000 tons of hot asphalt were used as the road surface , 28,000 tons of reinforcing iron and 13,000 tons of structural steel . The supporting structure is prepared in such a way that the route of a light rail system can be added below the lanes for road traffic.
