July 14, 2015: Completion of the four-lane US 20 across Iowa involves detouring the route through Galva. Detoured traffic will take a left while the road ahead will be closed. Photo is at the south end of old IA 328.
The plan to close US 20 for two consecutive years has been dropped in favor of restoring the regular route over the winter, the Sioux City Journal reports. The detour will be restored in the spring to continue upgrading the final stretch of 20 to four lanes.
