High Speed Two Publish Rural Footbridge Design
High Speed Two have published their rural footbridge design on this page of their web site.
This image from High Speed Two shows an artist’s impression of the bridge.
This is High Speed Two’s own thoughts on the design.
Made of weathering steel, the sides of the lightweight bridges will lean outwards to maximise views of the sky and improve the experience of people crossing the railway.
Weathering steel – which ages naturally to a russet brown colour – was chosen to help match the tone of the surrounding countryside, while the plates that form the structure of the bridges will be angled to appear narrower and lighter.
To emphasise the sense of lightness, each span will be slightly higher in the middle so that they appear to leap over the railway. Most of the bridges will consist of just one 42m span, with extra spans added where necessary to create bridges of up to 102m long.
The design of the bridge would appear to be a good compromise between accessibility, cost, ease of construction and installation and practicality.
The article also covers other topics.
Step-Free
This paragraph explains how the bridges will be step-free.
In order to improve efficiency of manufacturing and assembly, all the bridges will have the same basic form, with the approach paths built into the earthworks on either side of the bridge. This also means that all the footbridges will effectively be step-free.
I can see bridges of this type being built at other rural locations.
A Single-Platform Station
These images show James Cook station in Middlesbrough.
High Speed Two’s rural bridge design could be used as part of a design for a step-free station on a rural line.
Bridleways
The footbridge can be used for a bridge on a bridleway.
Designed with guidance from the British Horse Society, the bridges which carry bridleways will follow the same basic pattern, with a recycled, non-slip rubber deck and the structure acting like a baffle to stop horses being distracted by passing trains.
Footbridges will be 2.5m wide, while bridleways will be 3.5m wide to allow two horses to pass comfortably and safely.
It should be remembered, that horses are flight animals and if they are startled they run, so if say a train went under the bridge, when they were on top, they would most likely go forward and cross the bridge quickly.
I would happily have ridden my stallion; Vague Shot over a bridge like this.
I also think, the design of the bridge in the landscape should allow riders to approach to a safe distance from the bridge and perhaps watch a train or two go through.
Other Animals
I can see other animals like badgers, foxes and hares using a bridge like this.
I also think, that on classic railways, bridges like these could be used to allow farmers to move sheep or possibly cattle over a railway, with some simple design changes.
Conclusion
This bridge has more applications, than the initial one, for which it was designed.
The Anonymous Widower 
From the description I assume the steel is COR10 which weathers and then stops and protects the rest of the steel and needs no paint. It was developed for the North Sea oil industry.

There’s a lot of it about on the railways, like the Ordsall Chord bridge in the centre of Manchester.
