The Scale of China's (and the World's) Longest Sea Bridge

By Alexis C. Madrigal

As a wannabe marathon runner, the news that you could complete the 26-mile race entirely on a new bridge built in Qingdao, China blew my mind.

The Qinqdao Haiwan Bridge stretches 26.4 miles in spanning Jiaozhou Bay, nearly three miles longer than the Lake Pontchartain Causeway, which had held the record for longest sea bridge.

What I really needed, though, was a way of conceptualizing how long this bridge was relative to a landmark that I know better than the Causeway. For example, how would this bridge look in the Bay Area? In the map below, look at how relatively tiny the Golden Gate Bridge is when compared to that long streak of red.
