Skid road bridge building?

[sawguy21]

Can't do anything like that here. Moving water is a Riparian Management Area and that is sacred ground. One company got a hefty fine for accidently dropping a concrete block which, btw, was recovered, during bridge reconstruction.  Bridges have to be properly cribbed without silting the water or disturbing the aquatic life, even on private land.

I find that disturbing and amusing that you have such tight controls on what a person can do to avoid all silting and disturbance of aquatic life after seeing the rolling brown water caused by the heavy rainfall in the mountains to your west and south.  The flooding and near flooding near Calgary and Drumheller were certain to do more damage than a bridge or two being constructed or a concrete block being dropped into the river.

After all the rain we have had this past 10 days here there isn't a brook, stream, river or any body of water that isn't silted up big time. Not to mention the houses and roads that are also now part of same. We (family) were driving by this brook yesterday and for a good mile or more kept seeing what looked like ice chunks that are left after spring break up. Only it wasn't it was styrafoam or some such thing. Must have been instalation or something from the trailer park that was washed away.

 Alstead N.H. got hit real bad, I thake my bulk syrup to Bascomb's up there. We ended up with 18" of rain here in Leyden Ma. I looked at one job, where I have a cordaroy road 50 yds long and it held up real well. The water is filtering thru and hasn't floated it away  . It'll be a week before we get back to logging around here tho  .

Ya Ed I am between you and allstead. Don't know exact amount. But i figuire somewhere around 15-19" of rain. All i know is it was to much.

I did not want to start a new thread, so thought I would revive this one.

These photos are of the typical type of portable bridge structure most operations are now using on all weather

 

After either building cribs or setting down sill logs (preferred) the bridge is moved into place.

 

Both halves are lined up and joined together and the center gap is covered with a steel strip to prevent mud and gravel from falling into the watercourse.

 

The bridge is finished off when curb logs and/or guardrails are in place and delineators are placed on the end of the bridge.

These bridges are designed to handled at least 80 ton loads and come a variety of lengths, with 30, 40, and 60 foot being most common around here.

i used an old army truck bed for a bridge. it was 12 feet long or so and all i did was fold down the tail gate, then torch the sides down in the front of the bed and fold that end down with the bobcat. i just left the 8 inch tall sides up on the bed rails. they are hinged if a person wants a wider bridge you could fold them out and weld them in place.

anyway it was fast and it holds my skidsteer up with a load of logs on the forks.
