Bridge
I need to get a bridge to span an 18ft dyke.
It doesn't have to be too ornamental, functional is fine. Does anyone have a favoured supplier. Thank you, S |

Thank you, S Is that 8? or do you really mean 18? If so that is one hell of a span, especially if you mean it to take vehicles as well, no I know you didn't mention that, but 'functional' for what?

If you make it too wide, then at some time in the future, someone is going to try to take a vehicle over it :-(( If you make it too narrow to prevent the above, then you must take into account that at some time or other, it could be full of people and the bending moment at the middle will be enormous, so it must be thick enough to take in the stress and strain of its thickness material :-(( From the centre, will it be possible to take some support struts down at an angle into the banks on either side? Very difficult to judge just what would be suitable without a visit and knowing what, how, why and wherefore :-(( Brick Arch from the bottom with a keystone?????

Thank you, S Nice (American) plans for a wooden bridge at http://pacifi.ca/2060.html maybe you could get a local carpenter to build on for you - or maybe you are a DIY dab hand Or maybe you could use concrete : http://www.auburn.edu/~roberrb/creteslingers/ped.html Jenny |

Hello Serenity S I need to get a bridge to span an 18ft dyke. S It doesn't have to be too ornamental, functional is fine. S Does anyone have a favoured supplier. I don't think there's a "Bridges R Us" type chain. Your best bet is to open the yellow pages and find a local engineering works who'll be able to knock up something to suit your needs. You'll probably also need a builder on site to erect/install it, but that's something you can sort out with your engineer. -- Simon Avery, Dartmoor, UK Ý http://www.digdilem.org/ |

JB Probably the cheapest way to do it, it with 2 ex-telephone JB poles as the spans, fixed to vertical stobs driven into the JB banks, and planks nailed across the poles as the surface. JB Farmers often have a stash of the poles. Possibly, it's a shame the OP didn't give more details. I can't think of many private gardens with 18' dykes in them, so it could be a public garden or place where the public has access, in which case a home-made bridge might not be good enough. (From the insurance POV, certainly) Plus, the thing about telegraph poles is that they're usually removed because they've failed a safety inspection ('D' classified) which means they're unsafe to be climbed. I wouldn't personally trust them on such a long unsupported span for more than 1 or 2 people (think how many people you can get on a bridge!) for more than 5 years or so. -- Simon Avery, Dartmoor, UK Ý http://www.digdilem.org/ |

Think suspension! Rope is cheap.
