The IA 21 bridge over Wolf Creek is scheduled to be replaced in 2017. That’s all. The big infusion of money came with the US 30 work that is now complete.
The good news is that the Benton County plan includes preparation for four-laning US 30 from US 218 westward to IA 21. The style and location for an interchange at the former is still being discussed (the Youngville Cafe has to be protected) and there will also be a diamond interchange at the latter.
