The world’s longest sea bridge opened this month to drivers between Hong Kong and mainland China.

The 34-mile Hong Kong-Zhuhai-Macau Bridge consists of a 14-mile main bridge span, two other cable-stayed spans and a 4-mile tunnel beneath the Pearl River Delta. The tunnel is connected by two manmade islands.

The engineering feat took 420,000 tons of steel – enough to make 60 Eiffel Towers – and more than 1.3 cubic yards of cement. Construction began in 2011.

The bridge links Hong Kong, the city of Zhuhai on the mainland and the island of Macau.

It has been built to withstand winds of more than 224 mph and is designed to last 120 years. The project reportedly cost $20 billion.
