9. Portugal
The Vasco da Gama Bridge crosses the Tagus River just north of Lisbon, Portugal, forming an important part of Lisbon’s greater road network. It is the longest bridge in Europe and was opened in 1998.
The deepest foundation piles reach down 95 m (312 ft) below sea level, part of the engineering required to safeguard the bridge against earthquakes. (The biggest earthquake to hit Lisbon was estimated to be 8.7 on the Richter scale).
