It isn't a trivial task to build a long bridge with Geomag, unless... you use some sewing thread. Let's see how to proceed.

At first we need four columns like this (here there are two, shooted from different angles):

A couple of towers must be joined this way:

and here is how to join the upper side:

Tie the sewing thread to the upper rod:

then pass the thread below the base and install two squares as follows:

Then repeat the same operations on the back side:

Now add some sections on the sides of the tower, as follows:

The top of the tower should look like this:

Now it's the time to join two models like the one described above:

That's all! Now we can see some other shots of the bridge:
