The Confederation Bridge is a bridge that links Prince Edward Island with mainland New Brunswick , in Canada . It was constructed betwoon the 1993 and 1997 and the construction cost was C$ 1.3 billion .The bridge opened on May 31, 1997 and has a length of 8 miles (12.9 km) .
Most of the construction took place at staging facilities in Bayfield, New Brunswick and Borden-Carleton, Prince Edward Island. Construction began on October 7, 1993. Crews at the staging facility in New Brunswick created the approach bridges using precast concrete in steel forms, while the main bridge components – including pier bases, shafts, main girders, and drop-in girders – were produced on the opposite side of the Northumberland Strait, at the staging facility in PEI. Once the precast components were complete in July 1995, the forms were transported by water to the bridge site, and assembled in place by a twin launching truss with a one-of-a-kind travelling gantry crane called the Svanen. One of the most important structural elements of the bridge is hidden: a construction technique called post-tensioning was used to tie the pier bases, shafts, and girder together into one solid, continuous structure that is designed to last 100 years.
Construction crews reached an important milestone in August 1996, when the P22, or Navigation Span, was set in place by the crane, marking the halfway point of the bridge. On November 19, 1996, shortly before midnight, the last component of the Confederation Bridge was placed.
The bridge is a two-lane highway toll bridge that carries the Trans-Canada Highway between Borden-Carleton, Prince Edward Island (at Route 1) and Cape Jourimain, New Brunswick (at Route 16). The speed limit on the bridge is 80 kilometres per hour (50 mph). It takes about 10 minutes to cross the bridge. Tolls are paid only when exiting Prince Edward Island; the current toll rate is C$42.50 for a two-axle automobile, with other rates for different types of vehicles. Pedestrians and cyclists are not permitted to cross but a shuttle service is available .
The Confederation Bridge consists of three parts: the 1.3 kilometre-long West Approach Bridge leaving Jourimain Island, over 14 piers; the 0.6 kilometre-long East Approach Bridge leaving Borden-Carleton, over seven piers; and the 11 kilometre-long Main Bridge which joins the approach bridges, resting on 44 piers.
It is a multi-span post-tensioned concrete box girder structure. Most of the curved bridge is 40 metres (131 ft) above water, and it contains a 60 m (197 ft) high navigation span to permit ship traffic. The Confederation Bridge rests on 62 piers, of which the 44 main piers are 250 m (820 ft) apart. The bridge is 11 m (36 ft) wide. More Info on www.confederationbridge.com .
