Q: The Big One was manufactured by Arrow Dynamics. Construction of the ride began in September 1993 and lasted just over seven months. The tubular track and supports were airlifted from Bolton to Blackpool and stored at nearby Blackpool Airport. During the start of the construction of the ride, the south of Blackpool promenade was closed and pieces of the structure were stored on the road adjacent to the Pleasure Beach. The first pieces to be fitted were the large foundations that would follow on from the main supports. Once all the supports were fitted, the tubular track was fitted followed by additional supports on the turnaround and the mid course brake section. The ride opened to the public on 28 May 1994. For the first five years of its life, it was sponsored by the makers of the UK version of the soft drink Pepsi Max; until 1999. when the sponsorship ran out and the name was shortened to Big One and all traces of Pepsi Max were gone.
