The recently passed transportation bill includes money for the IA 100 bypass around Cedar Rapids, which has been held up at various points this century by environmental and budget issues. The Cedar Rapids Gazette says that while the money isn’t specifically allocated (ahem, earmarked) toward the project, the five-year plan included the construction on the assumption the money would come.
As for the endangered butterfly that held up plans in the past and necessitated a redrawn route? They can’t find any now.
