1. Magdeburg Water Bridge, Germany.
This is the world longest navigable aqueduct with total length of 918 m. The project was started in more than a hundred years ago, in 1905, but it was stopped in 1942 due to WWII.

After 6 years, 24 000 tons of steel and 68 000 tons of concrete, the aqueduct started operations in 2003. Since then it crosses over the Elbe River and connects the Elbe-Havel Canal to the Mittellandkanal, reducing more than 12 km (7.5 miles) of the distance passed by trading and passenger vessels.
