Hand-Made Driveway Bridge - Elba, MN, USA
 
My dad, I and a few other guys built 2 bridges: the 1st is a stainless steel driveway bridge, and the 2nd is a stainless steel walking bridge, both over the same ravine. Also, the driveway bridge can hold 90 TONS, it has 6 stainless steel I-Beams w/ 86 yards of concrete as a foundation. Enjoy. BTW, these were built at our house in Elba, MN, USA. Thanks for viewing!

The engineering done was only to calculate how strong the beams would have to be vs the length of the beams to hold as much weight as 90 tons. Then we added the verticle beams for additional stability support.

ALSO, I forgot to credit my stepmom. The top of the bridge was made from the expanded steel for the weight and this material never gets slippery with ice and snow does not accumulate for additional weight - it was her idea!

A few more details: The bridge itself is 120 feet and with approaches it is 160 feet. The walking bridge is 140 feet.

Wait a minute
You built that yourself? and it supports a car?
In a word, WOW.
I can't imagine the grief they gave you at the building office.

Hi Clutchcargo! Thanks for viewing so fast! Yes, we built them all by hand; no contractors, no advanced heavy industrial machinery except for the Readymix concrete. Just 5 guys, shovels, welders, etc. It supports more than 1 car at a time, at a maximum of course. We had to get some permits, and the Department of Natural Resources was out to check it out. Overall, a great experience and a strong sense of accomplishment. Thanks again!

It's not in New England - not a covered bridge :wink:

Nice work, was there something there before?

Hi Scuba Dave. The area immediately as the ravine was covered by scattered trees. The entire area is at the base of a valley in Whitewater State Park. We could have just scraped the ground, pressed it and poured crushed rock but why not make it a challenge. Thanks for the kind words and for viewing!

Great work! But wouldn't it have been cheaper to just buy a Jeep and drive through the ravine! :laughing: Hate to see the cost of the steel. Love to have seen the readymix guys face when he pulled up and saw what you were DIY-ing. :eek:

Hi WaldenL. The steel I'm sure was expensive. I'll have to get that figure and weight from my dad but I do remember we bought it and the beams stored for about a year. It was tough getting those beams out there too due to all of the valley roads and bluff terrain. The Readymix guys were a bit surprised but we inovated w/ a ply-wood structure. Too much fun. Thanks for viewing!

Holy cow. Talk about raising the DIY bar.

That definitely puts my high school popsicle stick bridge to shame.

KID STUFF!!

Here's the bridge I built, with nothing but my swiss army knife, a roll of baling twine, and a stick of Big Red

Nice work jrico01, very impressive

jrico01 09-24-2009 08:17 PM

:) Thanks for stoppin by! The irony being I never did get to build a popsicle bridge! -jrico

Chips... interested in selling that bridge? I may have a buyer. :laughing:

jrico01 09-28-2009 05:38 PM

Added a few more details!

Tigwldr 09-28-2009 06:56 PM

Why did you paint the stainless? It doesn't rust....


How long ago was this built. I like doing stuff like this project. Did it for a living until I started in the power turbine and boiler industry.

If you have to add details its best to just put them in a new post (or both)
Makes it less confusing to people who have already read the original posts
