The new crossing consists of: (1) the Sacavem and EN10 Interchanges in Lisbon (2) the 560m North Viaduct, of prestressed T-beam construction (3) the 672m Expo Viaduct, of glued segmental prestressed box-girder construction (4) the 830m cable-stayed Main Bridge across the Norte navigation channel (5) the 6531m Central Viaduct, with two 130m spans and many 80m spans (6) the 3635m South Viaduct, of prestressed T-Beam construction and (7) the 4672m southern access roads. The crossing covers 11km over water and 7km over land, and carries a dual three-lane highway, which will later become a dual four-lane road. The bridge was funded from various private sources. In April 1994, the Lusaponte consortium was awarded the Build-Operate-Transfer (BOT) contract for the new crossing, about 13km upstream. In 1991, the Portuguese Government decided that this bridge was needed to relieve serious traffic congestion on the 25 April Bridge. This article reviews one of the world's largest civil engineering projects, the design and construction of the 18km Vasco da Gama Bridge over the River Tagus near Lisbon.

The nature reserve Parque Natural do Estuário do Tejo with its waterfowl population had to be taken into account during construction.ģ00 families had to be relocated to clear the foreland for the new bridge. The overall project is financed with the fundamental inclusion of EU financial aid via a PPP financing model (public-private partnership) of a private consortium that receives the toll (model analogous to both Lisbon bridges) over 40 years in each refinancing, whereby The financing PPP capital for the younger Techo bridge was brought in with 24.8% by British companies, with 24.8% by French donors and 50.4% by Portuguese companies, with the Lusoponte company also operating in the model the bridge is involved.ĭuring the construction of the bridge, a fatal accident occurred on Apwhen a metal frame collapsed and six workers were killed. The Vasco da Gama Bridge is owned by the country of Portugal ( República Portuguesa ). The Expo site and the airport can be reached directly via the Ponte Vasco da Gama. The bridge was built between 19 for the World Exhibition Expo 98 in order to relieve the Ponte 25 de Abril and other Lisbon infrastructure from north-south traffic.

The A12 motorway crosses the bridge with six lanes. The maximum span is 420 meters, the pylons are 155 meters high. If you add the construction of the bridge with a length of 12.345 km to the construction of the road with a length of 4.84 km, the road traffic concept for this Tejo river crossing results in a route length of 17.185 km. The Vasco da Gama Bridge is one of the longest bridges in Europe and the world with a length of 12.345 km. Location of the Tejob ridges in the Lisbon region
