Cobblestone Bridge

Cost:

 * cobblestone: amount varies with size
 * rail track : as much as needed
 * fence: needs to be enough to cover the bridge
 * minecart
 * minecart with furnace

Introduction
This tutorial will teach you how to make a cobblestone bridge with a minecart system inside of it. It is very easy to make. Although the photo shows the bridge being 3 blocks wide, you can have it wider, so adust to the space that you have. The minecart is powered by a furnace cart.

Possible alterations

 * Have 2 seperate tracks on the bridge, each powered by a seperate furnace cart
 * use powered and detector rails: use these to replace furnace carts
 * remove tracks altogether: and save on iron ingots and sticks
 * add decorative parts such as supports
 * lights to stop monster spawning

Limitations

 * huge cost
 * can be hard to build in suvival
 * underground tunnels are just as effective
