Originally known as Project Odyssey, revisit the construction of the Intamin 10-inversion rollercoaster, Colossus, which opened in 2002 as Thorpe Park’s first major coaster.

1st November 2000

John Wardley’s Rollercoaster Tycoon recreation of what Colossus would look like, and views across the construction site where land clearing had been completed, along with the installation of the first piles and foundations.

4th December 2000

Further piles were being driven into the ground for the cobra roll trench. A model was installed at the edge of the construction site, providing guests with an insight in to how the finished attraction would look.

7th January 2001

Work on the foundations and footers had started, with a retaining wall built between the construction site and X:\ No Way Out, to allow space for the maintenance building to be constructed.

26th January 2001

Continued ground work and preparations for the raised walkway, which will span from one end of the coaster to the other.

6th February 2001

Concrete structures were now visible on the left of the site, with the queue line set to pass through the dark blue tunnel.

22nd February 2001

The majority of the footers for ride supports were now complete, and work was continuing on the trench for the cobra roll.

15th March 2001

A lot more concrete was now visible, and the raised walkway was coming together.

6th April 2001

The first photo shows the lift hill footers in place, with the raised walkway bridge progressing next to them. The track will pass under the bridge twice; after the vertical loop, and in between the two corkscrews.

16th May 2001

The paths leading up to the raised concrete bridge were being constructed.
