The longest ice bridge in the world: Beaufort Sea Bridge (109km)
Beaufort Sea Bridge is located in Alaska, USA, with a total length of 109 km. It is the longest ice bridge in the world. Time, perseverance and severe cold are all needed to build an ice bridge. Influenced by the TV series "ice road ahead", this kind of low-temperature ice road has come into everyone's view. However, this ice road across the Beaufort Sea connecting the oil fields in northern Alaska is made of all ice, which is really dangerous and unique.
The longest floating bridge in the world: changqingdian floating bridge (5358m)
Changqingdian pontoon, located in Seattle, USA, is the longest pontoon in the world. Completed in the 1960s, drive east along highway 520 from Seattle to Washington, and you'll pass the floating bridge on Lake Washington, which is the size of 33 football fields. The reason for this design is due to the influence of unstable river bed and natural undulating highway. Now it is gradually replaced by a larger and longer pontoon, which can even accommodate light rail tracks.
