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

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?

Yep an enormous span - 16ft sleepers won't cover it :-(
It is just to take people. No vehicles.

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 :-((

Try Cowleys of Lincoln.

18ft is in the realm of timber engineering.

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 :

Where does the poster indicate that the water in the dyke is troubled?

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.

Probably the cheapest way to do it, it with 2 ex-telephone poles as
the spans, fixed to vertical stobs driven into the banks, and planks
nailed across the poles as the surface. 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.
