Not as aesthetically pleasing as the old one, but still an achievement.
"The UK’s first stainless steel bridge, built by Eric Wright Civil Engineering, has opened over the River Eamont at Pooley Bridge in Cumbria. The 39m bridge reconnects Pooley Bridge with the Ullswater Valley, after the 18th century stone structure it replaced was destroyed during Storm Desmond in December 2015. The bridge was designed as a single-span structure to avoid the need for piers in the river, thereby reducing the flood risk and making the structure more flood resilient. In total, around 80 tonnes of stainless steel has been used, 2,000 tonnes of concrete laid, along with 650 square metres of locally sourced stone. Some 250 people have been involved in the project and the bridge has taken approximately 10,000 person hours to construct. Diane Bourne, managing director of Eric Wright Civil Engineering, main contractor for the project, said: “It’s always so sad when we lose a piece of history so it was really important that we built a new, modern bridge which would not only complement the local surroundings but which would ensure the communities either side of the River Eamont remained permanently connected for future generations to come. “The new bridge is slender and exceptionally strong and is designed to be resilient to any future extreme weather conditions. We’re very proud to deliver the UK’s first stainless steel road bridge and I’d like to thank all of the team for working so hard to complete this landmark project and to the local community for their support and patience.”" https://www.constructionmanagermagazine.co...completed/ Edit: Or maybe not if this one counts: The Celtic Gateway Bridge - completed in October 2006

A very interesting project indeed! would be interested to see the designs.

I agree with both of those sentiments, an interesting and stylish bridge but it jars in that landscape. I am sure that time will mellow it. A very interesting project though, but a version of the video aimed at the technical and engineering aspects would be more interesting to me. |

I like it. It's a nice simple design that shouldn't date like some 'cutting edge' stuff does.
The choice of material is interesting and I'd be fascinated to see more detail on that. I have some experience with using stainless steel structurally and it can be a tricky material to use successfully.

I accept that the aesthetics are wholly subjective, and I expect it will grow on me.

Agreed - personally, I think it blends in well - good job all round. |

Quite, was hoping it went into some of the technical details but it didn't. Hopefully, there might be more about this, being the first in the UK, from some of the more technically orientated feeds. |

I'll have a scan through the ICE publications to see if I can find anything more technical. I'm particularly interested in the grade of stainless used, as LandRoverAnorak says, it can be tricky material to work/design with. 1985 127 V8 Build Thread

I haven’t been up to see it yet but from the video and photos I think it looks very elegant . Thomas Telfords Iron Bridge was radical when built but also an elegant design. I’m sure that this new bridge will be seen in the future much in the same light.

^^ That is a very fair point.
 I bet Telford had his critics! |

Considering they didn't want any piers in the water this time around, a new stone bridge would have to have had quite a pronounced arch to it to span that gap - so probably not viable. A stone-clad concrete bridge would look a bit fake. So I think the choice of metal, and the elegant tapered arch is a beautiful solution, and fits in well with the stone abutments. I like it.

Reading a bit more about it ~ thanks to the link to the planning details
~ it's actually made up of two concrete slabs. Both the lower arch and the upper arch or deck are concrete. Only the girders encasing the edges of the slabs and joining structures are stainless steel. |

I too am interested in the use of Stainless Steel in the bridge, I have earned a lot of money over my career dealing with cracked and corroded stainless steel.
The grade of SS used, the welding details and post welding heat treatment and the loads on the sections will be of interest. Our natural environment and run off water from roads is full of salts and chemicals that may enjoy ruching through a stainless steel fabrication. But on a note re design, I think the stays close to the abutment will be a perfect collector of tree debris during flood spate conditions, exactly what you don't want in flood conditions as the debris causes river to back up. 130 Puma HCPU with an Artica 240LR Demountable Camper |
