Madeira International Airport in Portugal is a major civil engineering project. The airport's runway has undergone several remodels and expansions since 1964 to accommodate growing passenger traffic. Most notably, in 2000 the runway was expanded over the sea supported by 180 columns up to 70 meters tall, reaching a length of 2781 meters. This innovative engineering feat was designed by Portuguese engineer Seguedães Tavares and received international recognition, winning the IABSE Outstanding Structure Award in 2004.
