Cost Effective Replacement Bridge over Stream for Farm Traffic

[Robert]

I have just priced the steel to refurbish a stream crossing to carry all farm traffic (combine etc). Crossing is 4m wide so have allowed 1m either side: 6m long, 4.5 metres wide, sleepers laid on the universal beams.
Steel is going to cost £2,500 and a further £1,900 to galvanise it. With new concrete, sleepers, labour etc it ain't cheap!! I hear of people using old lorry decks etc - does any one have any alternative suggestions please? I presume proper concrete box culverts will be just as expensive and necessitate a crane etc..... Thanks

We used concrete panels similar width ten years and still going strong no artics but combine and tractor trailer grosing about 26 ton

Thank you. Don't suppose you've got any photos / sketch of design please? I presume you can't just lay normal precast panels across that kind of span to carry 26 tonnes - presume there's steels involved too? Thanks

New bridge,work in progress

Thought I’d share some progress pics of a river bridge we are having built by a local engineering company. It’s a 60ft single span, 15ft width. Previous one was washed away in last years floods leaving us no access to 77 acres of grass land. :(

No there was no steels involved probably a six meter panel over a 4-4.5 meter brook it's only 150 thick I would have preferred a 200mm one but I don't pay the bills. They are prestressed wall panels from Jones brothers in North Wales next time I am near I will get a few pics

There's a thread on here of a big bridge made , think it may have been ' colinv6 ' but not totally sure , was bit more major than yours though I think .

Probably best to talk to the panel makers to check the spec is up to the job

Weight??

 

[Robert]

25 tonnes?

 

[Mc115reed]

I think your over complicating the job here… go the scrap yard or a salvage yard, buy an old scrap bale trailer or artic trailer… cut the running gear off… hell even leave it on if you really can’t be bothered… hire a digger for the day, dig a hole either side too hold it… trailer 1 side, digger the other… chain across and drag it into place, bury the edges…

 

[Robert]

Just been looking at this approach. Is that going to carry 25 tonnes though if its a void underneath instead of 6 x 100psi super singles do you think?

Depends how big the ditch is your wanting too bridge I guess…

I have some 406x406 by approx 200 kg per meter UC about 10 meters long very good condition they originally had a concrete floor on them and was part of a first floor car showroom 4 of these side by side would be overkill

Blimey, I would not have expected that to work. What weight of stuff is going over it?

Heaviest is probably tractor and grain trailer 25-26 ton not everyday and only being a 4.5 meter span it's not all on the bridge at once

Only once it need to go through mind

Would cost quite a bit if you lost a 14t trailer of OSR at £580/t, let alone the cost of damage to tractor and trailer, delays at harvest, injury to driver, and/or HSE investigation.

Makes you think when you add it up like that…
