There’s a little detour to get around the future roundabout at old 30, and then there’s this project. US 63 from the north end of Toledo to just south of the IA 96 junction is going to be pulverized to bits and the entire roadbed rebuilt. The new version will have redone turn lanes at the Garwin corner, which now is home to an elevator complex and a John Deere dealership. There will also be multiple passing lanes instead of just the one at the intersection with the sign for the Lincoln Historic Marker.
The closure begins Monday and will last through October. Traffic coming east from Gladbrook that wants to get to 63 is officially detoured to Traer, making the east-west section of 63 both “southound” and “detour northbound”. Signage could be interesting.
The official detour uses IA 8, IA 21, and US 30 all the way to the east end of Tama County. Perhaps if work is divided at the E29 intersection, part of that can be relocated/shortened. Otherwise, just like the detours of the Depression era, there are gravel options. They’re just unofficial.
