China has built more than 800,000 highway bridges, and over 10,000 km of high-speed railway bridges.

There were 805,300 highway bridges across China at the end of 2016, Zhou Wei said, chief engineer from the Ministry of Transport.

Of the world's top 10 cable-stayed, suspension, arch and beam bridges with the longest main spans, seven, six, six and five are in China respectively, according to Zhou.

China had completed 22,000 km of high-speed railway lines as of last year, and bridges accounted for over 50 percent of that length.
