The 1915 Çanakkale Bridge in Turkey, opened in 2022, has the longest central span (2,023 m) of any suspension bridge.
The world's longest suspension bridges are listed according to the length of their main span (i.e., the length of suspended roadway between the bridge's towers). The length of the main span is the most common method of comparing the sizes of suspension bridges, often correlating with the height of the towers and the engineering complexity involved in designing and constructing the bridge. If one bridge has a longer span than another, it does not necessarily mean that the bridge is longer from shore to shore (or from abutment to abutment).
Suspension bridges have the longest spans of any type of bridge. Cable-stayed bridges, the next longest design, are practical for spans up to just over 1 kilometre (the longest cable-stayed bridge in the world has a 1,104m span). Therefore, as of January 2025, the 33 longest bridges on this list are the 33 longest spans of all types of vehicular bridges (other than floating pontoon bridges). (Full article...)

A sailboat or sailing boat is a boat propelled partly or entirely by sails. The term covers a variety of boats, larger than small vessels such as sailboards and smaller than sailing ships, but distinctions in size are not strictly defined and what constitutes a sailing ship, sailboat, or a smaller vessel (such as a sailboard) varies by region and culture. Apart from size, sailboats may be distinguished by hull configuration (monohull, catamaran, trimaran), keel type (full, fin, wing, centerboard etc.), purpose (sport, racing, cruising), number and configuration of masts, and sail plan. Although sailboat terminology has varied across history, many terms now have specific meanings in the context of modern yachting.
