Travelers who drive on Highway G-28 to get from Knoxville and Pleasantville to Pella and back may experience delays soon. Marion County Engineer Tyler Christian says there is planned patching coming up soon on the stretch of road from Highway 14 to the western city limits of Pella near the T-15 intersection. Christian says no firm date has been set, but he anticipates the work to take place sometime by the end of September.
