The tallest, fastest, longest single rail coaster is nearing completion at Six Flags and it looks awesome. Crews topped off the Jersey Devil Coaster that will open at Six Flags Great Adventure in New Jersey and it's only about a 4 hour drive from central New York. The new ride is 13 stories high with 3,000 feet of track and begins with an 87 degree first drop. You'll sit single file with your legs straddling either side of the monorail track, as you reach speeds up to 58 mph and experience a 180 degree stall and zero g-roll. “Six Flags Great Adventure is home to the best and most innovative roller coasters on the planet, and we are thrilled to expand our unrivaled collection with the Jersey Devil Coaster,” said Park President John Winkler. “
