One year ago today (January 26, 2009), workmen finished installing track on the Diamondback roller coaster at Kings Island. Track piece #129 was the final piece of track installed on the 5,282 foot-long $22 million steel coaster, being hoisted into place at 2:42pm. It took the Adena Corporation a total of 161 days to erect the ride after the first piece of track was installed in the splashdown area on August 18, 2008. Diamondback opened to rave reviews, giving more than 1.8 million thrilling rides in its debut season.
