The Ponte Vasco da Gama (German Vasco da Gama Bridge ) is a bridge with a cable-stayed bridge as the main opening that spans the Tagus River and connects Lisbon by motorway from Moscavide / Sacavém with the southeast and south-facing cities of Montijo , Alcochete and Setúbal . It was named after the Portuguese navigator Vasco da Gama and is intended to commemorate the 500 year old discovery of the sea route to India in 1498.
General
The Vasco da Gama Bridge is one of the longest bridges in Europe and the world with a length of 12.345 km . 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 maximum span is 420 meters, the pylons are 155 meters high. The A12 motorway crosses the bridge with six lanes.
The bridge was built between 1995 and 1998 for the World Exhibition Expo 98 in order to relieve the Ponte 25 de Abril and other Lisbon infrastructure from north-south traffic. The Expo site and the airport can be reached directly via the Ponte Vasco da Gama.
The Vasco da Gama Bridge is owned by the country of Portugal ( República Portuguesa ). 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.
During the construction of the bridge, a fatal accident occurred on April 10, 1997 when a metal frame collapsed and six workers were killed.
The nature reserve Parque Natural do Estuário do Tejo with its waterfowl population had to be taken into account during construction.
300 families had to be relocated to clear the foreland for the new bridge.
