It's crazy how much track work they got done this week compared to the rest of the construction. Just looking back at Monday and now to today the entire hill plus some is done and that's not really a short element.
I feel like the helix may take longer than a week to complete since there are so many more supports that need to be built compared to the mainly single supports that are on the hill before it, but we will see. Looking at the layout there are 11 multi-piece supports that have to be built compared to the three multi-piece supports on the hill prior. If the crews work on the next two Saturdays I could see them being done by the 31st, but if they don't I think the first (or second if the weather is bad) week of February is when track will be completed.
