MidwestInfoGuide has a recent update of photos that show off the slide's current status. The slide features one huge drop, followed by this large camel back hill. Then there appears to be a leisurely trip back to the station area.
There's plenty of other work going on, and as the update shows the supports for the main tower and drop are going in, too. The size of the main support is staggering when you see how tiny the staircases they are adding appear!
