Imagine you have a supply of perfectly uniform bricks of length 1, and you'd like to build a freestanding bridge of sorts. How far could this bridge theoretically extend if it is composed of bricks placed on top of once another in a single strip?
For example, a bridge made of 3 bricks resting on the ground would look something like this from the side:
. . . . ____
. . . ____
. . ____

reverse cantelever every other brick.
lay one brick down
place the next one 2/3 of an overhang.
place the next one 1/3 hanging back the opposite way
place the next one 2/3 of an overhang

It can grow infinitely, but, you need to counterbalance each brick with enough weight, so that no one brick tips.
So, every brick must have more weight on the overlapping part beneath it, than the part standing free (or else the obvious happens).
So, you just need to make sure that you add additional weight to compensate for all the bricks that you ad ...[text shortened]... a funny looking bridge, but it can get as long (and high at the same time) as you want it to.

HINT: Each subset of bricks must balance on that subset's foundation brick...try starting with the smallest subset and see what happens!
