The Robin Hill crawl tube was made from 304 stainless steel as well as having a satin polish finish. The crawl tube had a curved twist to it which made it come from one opposing side of the bridge to the other. This makes the crawl tube both challenging yet fun to the user.

The length of the crawl tube was 13 metres with a weight of 890kg and the steel was formed to be in a mesh style in order to help the user navigate themselves from one side to the other in the best way possible.
