Local traffic will no longer be able to use the stretch of Hwy 55 between Wright CR 12 and Hwy 25 in Buffalo as crews replace two large culverts/pipes beneath the road. The road will be impassable. They will replace one culvert/pipe at a time. Seek other side roads or use the official Hwy 55 detour.
