Yukon Striker
Yukon Striker is a steel roller coaster at Canada's Wonderland in Vaughan, Ontario. Designed as a Dive Coaster from manufacturer Bolliger & Mabillard, the ride opened to the general public on 3 May 2019 in place of SkyRider, a roller coaster that was removed from the park in 2014. Featuring a height of, a length of, and a maximum speed of, Yukon Striker is the world's tallest, longest, and fastest dive coaster, sharing its height record with Valravn at Cedar Point. Its four inversions and drop length of also set world records among dive coaster models.
History
Following the park's removal of SkyRider, Canada's Wonderland began preparations for a new ride. In 2014, the park requested a geotechnical investigation of the area, extracting soil samples to assess building a roller coaster's concrete foundation. On 19 December 2017, Canada's Wonderland filed an application for a permit to build nine support footers on the water and amend the waterway with a tunnel travelling under the pond within the park. A permit was required from the Toronto and Region Conservation Authority, as parts of the ride, and the pond beneath it, fall within the Don River watershed. The application was approved by the TRCA on 9 January 2018, with construction on the ride's foundations beginning later that month.The diversionary channel was built under the pond in order to facilitate the creation of the underwater tunnel, as well as prevent silt runoff downstream. Construction for the diversionary channel, as well as the ride's underwater tunnel, required the temporary removal of two track pieces and a few supports belonging to Vortex, a roller coaster adjacent to Yukon Striker. Work on the tunnel was completed before the park opened for 2018, with the installation of four track pieces and two water pumps to pump rainwater out of the tunnel. With the tunnel completed, the removed pieces from Vortex were reinstalled, allowing for Vortex to be operational by the time the park reopened for the 2018 season.
In July 2018, following continuous construction during the operating season, the park began teasing a planned announcement scheduled the following month. On 15 August 2018, the roller coaster was officially introduced to the public, with renderings and details about the ride revealed. Construction for the roller coaster was completed on 4 February 2019, with the installation of the last track piece onto the 360-loop. Installation of the ride train, and landscaping of the surrounding area began after construction was completed.
On 24 April 2019, seventy-two people who helped raise funds for The Hospital for Sick Children were invited to test-ride Yukon Striker. In the days that followed, members of the media from Ontario, and neighbouring Buffalo, New York, were invited to ride Yukon Striker. The ride was later opened to the general public on 3 May 2019, during the park's opening day for the 2019 season.
Characteristics
The ride was designed by Bolliger & Mabillard, with the Canadian construction firm, E.S. Fox, contracted to build the ride. Secant Engineers, a local structural engineering firm, was contracted to design the ride's tunnel, as well as the ride's foundations. It is the first Dive Coaster to be built in Canada.The steel track is long and the lift is high. The track is made up of 107 individual orange-coloured steel track pieces, the total of which weights 1,213 metric tonnes. There are 42 support columns used to support the ride. The steel used to build the roller coaster originated from Clermont Steel Fabricators in Batavia, Ohio.
