The Vasco da Gama Bridge crosses the Tagus River between Sacavém on the north bank and Alcochete and Montijo on the south bank in Portugal. Armando Rito designed it, with architects Michel Virlogeux, Alain Montois and Charles Lavigne. The Portuguese Republic owns it, and Lusoponte maintains it from 1994 to 2030. Construction began in February 1995, and the bridge opened on March 29, 1998.
It is a cable-stayed bridge with viaducts and cement pillars, and it carries six road lanes. The total length is 10.7 miles (17.2 kilometers), and the main span is 1,378 feet (420 meters).
The article does not name an architectural style. The structure combines the cable-stayed main span with long viaducts on both banks of the river.
