its true the structure required a lot of work along with modern evac platforms around the entire route, but once Thorpe closed it for so long they couldn't re-open it based on cost and the water ride water rules, if it hadn't closed it would have been fine but to reopen ot build a replacement water ride on the site needs a closed water system in place that is treated. Its not practical with the area for the water not to contaminate the lakes, the water from both lifts drain to the lakes, the water is pumped from the lakes etc
