well, the creek I'm talking about probably 160 - 260ft width.
Is it a big construction work?

Sounds like quite a creek. We just had a bridge put in.
If your creek/river is that distance. It would be cheaper to buy a boat. A very large boat. Or even a house boat would be cheaper.
I will post a picture of our bridge crossing a small creek.

This bridge originally was estimated to cost $126,000. 10 ton capacity. Ended up costing a little less than $140,000. USD. You can use the search engine on this forum if you want more pics. Just search New Bridge.

Quoting: mj1angier Need to call the Army engineers.
Plus quite a few other Gov. agencies.
EPA ,DNR, water way engineers, local government people, yadda yadda etc.
Mine spans 50 feet. So if you do the math........
You should buy a boat. Just my opinion.

Fib, how deep is the creek? You might be able to build a low water bridge if the flow is always very low. Concrete or metal culvert pipe is laid on the creek bed and concrete is poured over. When the creek rises, it flows over the bridge. Can you post some pictures?

Get an Argo. Heck of a lot cheaper even though they can get expensive. 2nd benefit is no uninvited visitors.

Our creek is about 40-50’ across.
A friend welded galvanized channel steel together to create our bridge (about 56-60’ long x 7’ wide). It’s sturdy enough for regular ATVs to cross it.
If the creek is that wide and only people need to get across it, could you just use a sectional pier across it? (When our lake water went down for a number of years a neighbour put out a pier that was about 500’ long.
With a pier you could pull it out if there’s any seasonal flooding or freezing issues.
Or... would maybe a lightweight cable suspension bridge of some sort work?

Maybe a raft or cart and cable / winch system would work well. Put wheels under the raft if there are shallow spots.

Just had a thought. For narrow creek crossings would a pole-vault and rope type of system work?
Say two tall stilts (stiff steel or wood poles) set to pivot on one side of a creek with a platform to stand on hanging in-between. Add a wheel like you’d find on a boat lift to spool up the rope and swing yourself across.
Yes, an overhead cable and a basket hanging from it might be a simpler solution.

Although only about 25 feet long, we have a spot that is a ravine beside the cabin. In the spring up to about July, there is a creek that runs through it with a little water fall. We built a causeway over the ravine by placing rocks across and building it up. We used a block and tackle and lots of man power to get the large rocks in place. It is about 4 feet high at the lowest point. The water ready runs through it in the spring. It has been in place about 35 years now and has stood the test of time.
I certainly would not want to tackle 160 feet though!!
