That depends a lot on the complexity of the ride. It also can depend a lot on the weather. The 2 rollercoasters going into SFGAm are relatively simple installations. However due to bad weather early this winter season they have not gotten far. If you want to see a rollercoaster being built and the process it takes to do so I would recommend going to
www.dorneypark.com and checking out Talon. Now that is a complex ride but they have not had the bad weather the Chicago area has had.
