Fisherman's Bridge is remarkable in many ways. It's not a large structure, spanning only 15m, and a mere 0.9m wide, but it's still quite staggering that it was built for the tiny budget of only £18,000.
Structurally, it is almost absurdly simple, a simply-supported weathering steel box girder, triangular in elevation and in cross-section at mid-span. I think it's fair to say that it's design hasn't been limited by the standard 5kN per square metre load normally used in the UK.
The structural engineer was Rob Nilsson of Price & Myers, while the architect was Ralph Parker of H-o-n-e-y.
carrying a tubular handrail, comply with none of the usual requirements, being both easy to fall through, and easy to wobble. That's a good thing, I think.
The rods alternate either side of the handrail to provide some stiffness, but also give a first impression that the bridge has been assembled in a haphazard, jumbled manner.
The steps at either end consist of slate slabs set in concrete, and attempt to raise the bridge clear of the river's flood level. However, the video below, made in November 2009, makes clear that it is not quite high enough!

That's pretty impressive, especially when you see how the bridge is attached to its supports, with simple, slender vertical plates.
When I first saw a picture of the bridge, I was disappointed by the triangular rather than curved profile, but up close, quibbles dissolve. It's an entirely singular structure, although I am reminded a little of a similarly rusty, non-standard private footbridge in the US.
specially composed tune, made especially effective because the box girder acts as a resonant cavity.
It's a crying shame that the bridge has received so little attention (although it was shortlisted for a RIBA 350 Award in 2010). I think it's one of the most interesting footbridges to be built in the UK in the last few years, a delightful little haiku in Cor-Ten.
