Speed limits through sections of Iowa 2, however, are posted at 25 mph, as vehicles must traverse a unique, temporary solution that involves permeable rock laid on top of the existing highway surface, with concrete barriers holding the rock in place.
The area remains susceptible to flooding, officials said, noting that the highway may close again or traffic patterns may be adjusted with short notice.
