Iowa 22 west of Wellman will be closed for two days next week because of road construction. The Iowa Department of Transportation says the replacement of a concrete culvert is the reason for the closure. Iowa 22 will be detoured at Kalona south on Iowa 1 to Iowa 92 west to Iowa 149. The closure begins on Tuesday. Iowa DOT maintenance crews will place gravel on top of the new culvert and seal it with oil. This repair will be allowed to settle for one month, and then Iowa 22 will be closed again for two days to allow for the final concrete repair. The project is expected to be completed September 1st.
