Remix and add more upgrades and interstates (the next one is Interstate 69). Interstates must be in order and when one interstate is done, another starts. They are measured by mileage in this game. Change Log: Version 30: Added a description that needs more scripting. Version 31: Fixed Rules (they go for all game items): 1 and 2. Those rules in the instructions. 3. Please, do not change, delete, or get wrong highways (INTERSTATE 1 DOES NOT EXIST). 4. Existing or if you must, future, MAJOR highways only 5. Helvetica only for Interstate number fonts, please. It looks the most realistic. 6. Please don't change the background.
Credit to everyone.
