The residents are already confused over these roundabouts. Now they are talking about adding additional signage and strippers. I'm sorry, but I don't think strippers will do anything but further distract drivers. Mount Vernon to Add Signage & Stripping to Roundabouts | KCRG-TV9 | Cedar Rapids, Iowa News, Sports, and Weather | Local News MOUNT VERNON, Iowa - The city of Mount Vernon is looking to make some changes to the roundabouts on U.S. Highway 30. Last week officials, including the Iowa DOT, decided to improve signage and stripping at the roundabout locations. City leaders hope the improvement will help drivers better understand the roundabouts. Officials say drivers' comfort levels will improve in time. Work on the roundabouts will start Friday.
