Bridge over a small brooke

[Maxus]

A client of mine wants to build a bridge over a small brooke. It will provide vehicular access to a field and will need to support the weigh of a tractor. The brooke floods in winter. I think the cheapest and easiest way would be to use large a large diameter pipe and somehow encase in concrete. Anyone have any experience with this and can suggest a design/material choice?

We did a bridge widening last year 400mm plastic corrugated pipe i think, concrete surround then sub base backfill. No movement with large concrete wagons etc but the water is a reen so not running water

We have use an lorry artic trailer cut wheels off and put on concrete each side when we were not allowed to pipe it for a temporary bridge but for a permanent bridge we have put in 2 RSJ shuttered up and renforced concrete over

If it's a water course piping it will need environment agency permission

i think its only improvments

Not sure on that one.. but I will definitely find out for sure before any work takes place. Its a channel that branches of the main brooke and then recconects. Its original purpose was to supply water to a mill, not sure how it would have powered a wheel, I think there must have been a pond of some description nbecause the volume of water flowing is minimal.

This is where the channel branches of from the brooke. This picture was taken in spring.

Great info.. yes the leet/leat needs a bridge over it.

many leets/leats were almost entirely covered ..... can think of two four examples locally, off the top of my head ... two are a hell of a length ... several hundred yards

This one isn't far off. I'm hoping the lady of the house will have pockets deep enough for me to dredge it, cut back foliage, and get it flowing again nicely. In the picture I posted earlier in the thread the water fall is the brooke and the leat branches off to the left (top of the picture). It looks like a large stone has become dislodged which will have the effect of limiting flow into the leat. I was also thinking installation of a wooden sluice of some description (see below picture) might be an interesting project and forming a large pond downstream next to the house. I'm sure that a sluice would require some kind of permission.. but maybe not?

well you'd be repairing an original feature, surely

Beaver bridges aren’t that dear priced me a big 6m long bridge for tractors was only £8k supplied.

Normally a few used bridges on eBay as well

Boy they new what they were doing back in the day when it came to this sort of thing. Leats near me stretching for miles all stone lined and following the contours of the land to a T,

These twin wall pipes are pretty handy tbf for piping watercourse. And no issue taking tractor and trailer over it as long as they're bedded in well pack the sides and nothing that can push down through the top. One I did back in winter. No concrete here but headwall needs to be substantial whatever it is.

Thanks for all your input so far. Here are some more pictures of the site incase you're interested.

Looks like where the existing bridge is potentially where there was a water wheel and/or a sluice gate. Not sure..
