   / build a bridge, get over it #62  
I am impressed with your work on this project. I am planning to build a bridge across a creek on my property also. The span is 65 feet with a 6 foot height. There used to be a state highway bridge here that was abandoned 60 years ago. One of the footings which is a massive piece of concrete about 20' square by 6' high is all that remains of the old bridge. I have found huge chunks of concrete from the other footing and the bridge washed 200' downstream although most of the second footing and bridge have dissappeared. I suspect that a lot of it is burried under tons of rock, sand, and gravel and more of it has washed even farther downstream. I plan to use the remaining footing and pour the other. This bridge will have to be all concrete to withstand the floods. I am hoping to get by with spending aroung $10K but I am probably way underestimating what it will cost me to build it. One thing that has me worried is how I am going to pour concrete under water as this stream is year round although it is not real deep (2-3' at the site of the bridge.) It rises as much as 20' in major floods and 6'-10' once or twice a year.

wow /forums/images/graemlins/shocked.gif you are dealing with a lot more water than me, my stream drys up during july and august if it doesnt rain a lot. What i can tell you is look downstream clear anything that will back up water, if water backs up to the bridge it will find a way around. most of the time by digging out the dirt on both ends.

the best that i can do is say what my mom used to tell me, "lord willing and the creeks don't rise, you will be just fine" /forums/images/graemlins/smile.gif

Re: another update on the bridge project

I had trouble getting dirt to pile up to the proper level i wanted, so i desided to build a retaining wall for the dirt. i rented a post hole digger and sunk rail road ties as far as the post hole digger would go. shear pin would break at about 4 to 5 ft, solid slate does that. /forums/images/graemlins/grin.gif

Re: another update on the bridge project

here is a photo showing the ties stacked up on one another, i stagered 10ft and 14ft ties and drove rebar through them to hold them together. as you can see i still am piling dirt up to get where i want it.

Re: another update on the bridge project

If you get flooding, do you have any culverts or anything to allow water to pass through your retaining wall?

You may have answered this in a previous post, but do you have the current cost of your project?

Re: another update on the bridge project

This is a great looking bridge, I have been following the progress, because I need a bridge myself. However, my creek bed is surrounded by flood plain, so unless I built a bridge a couple of hundred feet long, it will be under water every now and then. Any way a bridge can withstand that? The water doesn't seem to move as fast the higher it gets, but the low area looks more or less like a lake for a few hours while its raining (I'd like to see some of that rain right now - the creek's dry).

I have a low water crossing for the tractor, and don't really plan on vehicular traffic over the bridge. Could just be for pedestrian traffic, and maybe the riding lawn mower.

Re: another update on the bridge project

actually i do have one 10" drain pipe at the low end of the wall just incase water does get up in the field.

cost is a little over two grand for materials, but labor, boy there is the real cost.

it's good for me though, if i didn't do all this stuff then i would be just setting and watching tv.
