"There's always the temptation to create something oversized to
be sure the structure is strong. But that's not what model railways
are about. The bridge has to be as near to scale as feasibly
possible." (Barry Cole)
Using original blueprints, when available, and computer aided
design tools, these bridges are fine examples of craftsmanship
and attention to the smallest detail.
The Navajo Bridge (center) crosses the Colorado River's Marble Canyon near Lee's Ferry in the US state of Arizona. Apart from the Glen
Canyon Bridge a few miles upstream at Page, Arizona, it is the only roadway crossing of the river and the Grand Canyon for nearly 600 miles
(970 km). The Victoria Falls Bridge (left) crosses the Zambezi River just below the Victoria Falls. The river is the border between Zimbabwe and
Zambia, the bridge links the two countries and has border posts on the approaches to both ends, at the towns of Victoria Falls, Zimbabwe and
The model (right) is approximately 1.40 metres long. (Watch the video below to see a similiar bridge with a Warren Truss Bridge below it)
The highest railway bridge in Switzerland, theSitter Viaduct (99 metres high) is like many tall railway
bridges in Europe where large stone arch approaches give way to a long deck truss that sometimes looks
a little out of place. This model was built in honour of my Swiss wife, Heidi.
TheSitter Viaduct model is approximately 1.35 metres long.
The classicAmerican Warren truss was patented in 1848 by its designers James Warren and Willoughby Theobald
Monzani. Its configuration combines strength with economy of materials and can therefore be relatively light.
One of the earliest uses for the Warren truss design in aircraft design was for the interplane wing strut layout, as seen
in a nose-on view, on the Italian World War I Ansaldo SVA series of fast reconnaissance biplanes, which were
among the fastest aircraft of the First World War era.
The Warren Truss Bridge model is approximately 0.70 metres long. (See video below)

Here is a Youtube video from Union Pacific's
Feather River Canyon.
A little about Feather River Canyon- Was owned
by the Western Pacific Railroad. Was the route
the original California Zephyr took. It runs
between Oroville, CA and Portola, CA. Union
Pacific has named it the Canyon sub. It runs
BNSF from the valley up to Keddie where it then
branches and makes the BNSF Gateway sub.
It's an awesome place to railfan and I think you
will agree when you see this video.

bridge near a Navajo Bridge design.
