Previous to the visit to Hangzhou Bay Bridge, professor Xinli showed us a documentary film about Hangzhou Bay Bridge. This film revealed how the successful construction of the bay bridge represents a milestone in engineering field. Hangzhou Bay bridge is so far the largest cross-sea bridge in the whole world, with a total length of 36 kilometers. It shortened the ground transportation distance from Ningbo to Shanghai by an incredible length. This bridge marks the more expanded economy for regions around the bridge.

The most astonishing part about Hangzhou Bay Bridge is how all the strained circumstances were all overcome by engineers’ intelligence. The construction of Hangzhou Bay Bridge had encountered tons of problems, more than what engineers expect initially.  The eruption of natural gas in a shallow layer along the bridge line, the unpredictable severe weather above the sea and special construction material requirement are all the obstacles that keeps the bridge from being completed.

Our bus drove on the bridge on the way to Shanghai. Looking out from the bus window seat, I felt the pride for being an engineer because we are ready to solve the challenges all the time.
