3. Aqueduct Veluwemeer, Harderwijk, Netherlands 

The Veluwemeer Aqueduct is 25 meters long by 19 meters wide and its design allows constant traffic flow both on the road and in the water. Opened in 2002, this shallow 3-meter deep water bridge allows for small boats and other water vehicles to pass with ease. Engineers selected this design to other waterway passage techniques as a tunnel would have required much more time and effort with the same end result, and a road bridge would have meant a larger budget and longer construction.

9. Rialto Bridge, Venice, Italy

The Rialto is the oldest of the bridges that span the Grand Canal. In 1591, when Antonio da Ponte submitted his design, the engineering was considered so outrageous his peers practically laughed him out of his gondola, predicting that the bridge would soon fall down.

10. Henderson Waves Bridge, Singapore

This ultra-modern foot and cycle bridge was built to connect three parks and gardens located in the hills of Southern Singapore.

14. Magdeburg Water Bridge, Germany

The longest navigable aqueduct in the world at 3,012 feet, this water bridge was completed in 2003 to connect the Elbe-Havel Canal to the Mittellandkanal. Construction was initiated in the 1930's but World War II and the division of Germany thereafter suspended work for more than 60 years.

15. Falkirk Wheel, Scotland

The Falkirk Wheel, that opened in 2002, reconnected the Forth and Clyde Canal and the Union Canal for the first time since the 1930s. The wheel raises boats by 24 metres (79 ft), but the Union Canal is still 11 metres (36 ft) higher than the aqueduct which meets the wheel. Boats must also pass through a pair of locks between the top of the wheel and the Union Canal. It is the only rotating boat lift of its kind in the world, and one of two working boat lifts in the United Kingdom.
