Most big coasters fly down the track at 60 MPH or more. Second thing to consider is the fact that roller coasters are EXPENSIVE to make, with modern steel coasters costing more than $20 million to build. The more track you put up, the higher the cost, so designers, of course, have to limit the length of the ride.

In 2026, the cost of a modern "Giga" or specialized coaster often exceeds $30 million due to extreme engineering requirements and material costs. High-grade steel prices and the complexity of Linear Synchronous Motor (LSM) launch systems, which replace traditional lift hills, represent a massive capital investment. Furthermore, the safety testing and computer-aided design (CAD) required to ensure heartline rolls and zero-G stalls are safe for millions of cycles are incredibly labor-intensive. Beyond the track, "theming"—which includes sophisticated animatronics, 4K projection mapping, and synchronized audio—can double the initial price. As insurance premiums for high-thrill attractions have surged in 2026, parks must also pay for redundant sensor systems and fail-safe electromagnetic braking, making these engineering marvels some of the most expensive non-infrastructure projects in the world.
