How to Build a Bridge in GP4

"GP4," or "Grand Prix 4," is a Formula One racing simulation game from Atari. Players can play with up to eight others and race on a number of challenging courses. Players can create their own courses by using a program called GP4Builder. You may change already-existing maps and terrain in any way you desire. Bridges can add challenging aspects to your course as well as give it a more unique feel. To create a bridge, you will need to edit an already-existing game map.
