Things You'll Need
Instructions
Attach your current tracks to the bridge bases, called risers, by securing the tracks on top of the bridge riser. The set comes with four sets of risers in increasing height. Attach the risers where the tracks connect.
Use the bridge risers from shortest to tallest to create increasing and decreasing bridge height. The tracks will not work well if you only use the tallest riser, the tracks need to rise and lower to the ground gradually, so use multiple risers to get taller and longer bridges.
Attach the ascending curved tracks at the very beginning and very end of the bridge with the lowest riser as the base. This will be where the train climbs up to the bridge and then drives down off the bridge.
Secure the bridge trusses, the blue fences, to each side of the tracks on the top of the bridge. These can be placed in any straight track you choose.
