Can we make a portable bridge? (Model)

What is the material required?

What are its advantages and disadvantages?

Thanks in advance.

Lego? I'm afraid I don't understand the question.

 

If you just carry a plank, you have a portable bridge, right?

Define "portable bridge". All bridges can be disassembled, transported and resassembled somewhere else. Bridges themselves capable of controlled motion involving motors and steering are more vehicles than bridges.

 

Military pontoon brigde constructed for temporary usage and portability:

 

Transportable "bridge" on water called ferry:

I meant something which can be taken on a moving car and later unfolded at spot but still remains attached to car. This bridge can later be taken back by folding and using the car.

LOL

That's quite a bit more specific!

 

During WWII there were several designs of foldable bridges which were carried by tanks, and also strong enough to allow a tank to pass over them.

 

Just search for [wwII bridge tank] and you'll find some pictures and websites.

 

Whether it's possible to remain attached is another thing. I think it has some practical problems, and I don't see why it would be necessary.

Most definitely not just WWII era.

No, but I don't think they were widely used before WWII.
