Motorists wishing to bypass the construction are encourage to use the official detour on WIS 75, accessing it by way of WIS 20 or WIS 11. As the closure of County C is limited to near US 45, motorists wishing to access businesses in that area are encouraged to use County C, rather than US 45, whenever possible.
