Tri-Bridges Around The World
This post only shows twelve (12) newly
found Tri-bridges which have recently been added in my "Tri-Bridges Around The World"
collection. All the 25 bridges including details of these bridges can be found
in the
earlier post which has been fully revised and updated.
A few years back I got interested in 3-way or Tri-Bridges often referred as Tridges. These bridges have a distinct "Y" or "T" shape and span two water streams or a single body of water/lake with traffic from 3 directions merges/demerges at the Tri-junction and one can travel from any direction to any direction.
There are not many such bridges in the World. In 2009 I had made a post here and at that time I could locate only ten (10) such bridges. My hunt for these bridges however continued and till 2012 I was able to find
Thirteen (13) bridges. I recently got lucky and found 12 more bridges.
It is also pertinent to note that many Y-Bridges are just fork bridges wherein the traffic from one direction bifurcates in two directions or vice versa and there is no three way traffic. Similarly in recent times few 3-way interchanges have also been built. It is debatable whether a 3-way or T-interchange can be classified as a Tri-Bridge or not. In a classical sense T-interchange is not a Tri-Bridge as the interchange is built at 3 levels to allow unhampered 3-way traffic and there is no physical merger/de-merger of traffic over the trisection point. As a matter of fact there is no physical tri-section point. On the other hand all the conventional Tri-Bridges have a distinct "T" or "Y" joint and form a tri-section over water. I have therefore added only the conventional 3-way bridges.
Newly added bridges are;
Road Bridges:
- John B. Whealton Memorial (aka Chincoteague) Causeway, Chincoteague, Virginia
- Mangakahia Twin Bridges, Nukatawhiti, Northland, New Zealand
- Pierre Corneille Bridge, Rouen, France
Foot Bridges:
- Bergues Bridge (Pont des Bergues), Genève, Switzerland
- Bridge With 3 Branches (Le pont à 3 branches), Pont-de-Veyle, France
- Kang Ding Tri-Bridge, Kang Ding, Ganzi, Sichuan, China

Jiaozhou Bay Bridge (3-way Interchange), China
For sake of comparison I am giving below GE image of Jiaozhou Bay Bridge
- 3-way Interchange (aka Qingdao Haiwan Bridge), China. The image clearly shows
T-interchange but no physical tri-section. Guinness World Records lists the
Jiaozhou Bay Bridge as the world's "longest bridge over water (aggregate
length)" at 41.58 km (25.84 mi). (Wikipedia)
