Tri-bridges around the world

I spent my teen years living Midland, Michigan (where my parents still reside) and was well-aware of the “tridge” downtown; a bridge with three legs, sometimes known as a “Y-Bridge” or “Tri-Bridge”.


A while back, ‘CuriousJM’ put together a nice post about Tri-Bridges around the world on the Google Earth Community.  Along with the list of tri-bridges he also posted this excellent KMZ file to help you find them all.  Here’s the list.

Road Bridges
Aioi Bridge, Hiroshima, Japan
Bridge with Three Entrances (Ponte das Três Entradas), Portugal
Chu Y Bridge, Ho Chi Minh City, Vietnam
Hama Bridge (Sancha Zijin), Heicheng Village, Hebei, China
Jasenovac Tri-Bridge, Croatia
Louisa/Fort Gay Tri-Bridge (Kentucky/West Virginia), USA
Margaret Bridge (Margit Hid), Budapest, Hungary
Y-Bridge, Zanesville, Ohio, USA

Foot Bridges
Kikko Bridge, Mie, Japan
The Tridge, Midland, Michigan, USA
The Tridge, Frog Island Park, Ypsilanti, Michigan, USA
Treponti, Comacchio, Italy

Disused Bridge
Trinity Bridge, Crowland, Lincolnshire, England

Proposed foot Bridge
Hacking Ferry Bridge, near Mitton, Lancashire, UK

Google Earth is a perfect tool to explore items like this, and his list makes it easy to browse around and check them all out.

Nice work, CuriousJM!

  1. There is also a pedestrian tri-bridge in Manchester, England, at the Lowry Hotel crossing the River Irwell.

  2. Also missing is the Bhumibol Bridge in Bangkok, which crosses the Chao Phraya river twice at a long river bend and has an additional entry in the middle to connect with the other shore of the river. 13.6599 N 100.5390 E

  3. Jan Boerefluitjes says:

    Hellegatsplein and Grevelingendam in the Netherlands both deserve to be on this list!

  4. And another at the Millennium Bridge in Lancaster, England.

  5. There is also the Ypsilon pedestrian bridge in Drammen, Norway

  6. Many thanks Mickey for bringing up this post about my Tri-Bridges Collection. My apologies for such a late response. Hazel (Noisette, moderator of GEC) had brought this to my knowledge, but at that time I was in hospital for Angioplasty and had book-marked this page for reply at a later date. Unfortunately I totally forgot about it and came across my book-mark only couple of days back.

    I am thankful to your readers for for their suggestions. I have checked all the locations and some of the suggested bridges can definitely be classified as Tri-Bridges while the others are basically 3-way interchanges or do not form a Y or T over water.

    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 trisection 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 also realise that in all likelihood the future 3-way bridges in heavy traffic areas will be T-Interchange bridges as conventional Tri-bridges cannot cater to large flow of traffic. However as my collection is about the conventional Tri-Bridges I am thinking of not including such T-interchanges in the collection.

    My comments on individual suggestions are;

    @ Sladys – Trinity Bridge, Greater Manchester ( ) designed by renowned Spanish architect, Santiago Calatrava, has no tri-section over water. Like any other normal bridge there is only single path spanning a single water channel. It has two approaches which gives it a tri-bridge like look. Normally Tri-Bridges span over two water channels or have three sections connected to each other over single water channel. In my opinion it is not a Tri-Bridge.

    @ Andreas Hörstemeier – Bhumibol Bridge ( in Bangkok is an Interchange over land mass than a Tee or Y over water and in my opinion it is not a Tri-Bridge.

    @ Jan Boerefluitjes – Hellegatsplein ( and Grevelingendam ( in The Netherlands are Interchanges over land mass than a Tee or Y over water and in my opinion these are not Tri-Bridges.

    @ Matt Fletcher – Millennium Bridge ( over River Lune in Lancaster, England spans only a single water channel but its three paths create a Y over water. In my opinion it is a tri-bridge and I will add it soon in my collection.

    @ Sladys – Ypsilon pedestrian bridge ( in Drammen, Norway although spans only a single water channel but its three paths create a Y over water. In my opinion it is a tri-bridge and I will add it soon in my collection.
