The Jiaozhou Bay Bridge is considered the longest bridge in the world over water using aggregate lengths standards (parts of it are suspended over dry land). This bridge is 42.6 kilometers (26.5 miles) long but spans over water for only 25.9 kilometers (16.1 miles). It’s also the other bridge that competed with Lake Pontchartrain Causeway over which was the longest bridge over water, causing Guinness to create two longest bridge over water categories.
