Riding on the heels of successful innovations like
Corkscrew at
Knott's Berry Farm, which in 1975 was the first modern looping roller coaster in the world, Utah-based Arrow Development was hired by
Geauga Lake amusement park to design and build another industry first. Simply entitled Double Loop, the new design would become the first roller coaster in the world to feature back-to-back
vertical loops. It was introduced at the park in 1977 at a total cost of $1.35 million. The ride featured a , a helix, of track, and two vertical loops with one measuring in height and the other measuring . Double Loop would be followed by the park's very own Corkscrew roller coaster – one of fourteen identical installations eventually produced by Arrow – which opened the following year in 1978. Both gave Geauga Lake the title of becoming the first amusement park to feature multiple looping roller coasters. Double Loop's support structure was originally painted white, but would later be painted dark to match the track. The attraction debuted with two trains, one red and the other yellow. In 1993, the coaster underwent refurbishment adding some modernization to the control system. The outdated relay and photo eye controls were replaced with newer proximity switches to help improve reliability and to reduce downtime. Following Geauga Lake's acquisition by
Six Flags, Double Loop was given a makeover in 2000, with a new paint scheme featuring a yellow track and purple supports. The yellow train was repainted a darker shade of yellow, while the red train was converted to purple. ==Track layout==
