Starting Wednesday, Grey County is closing a section of Grey Road 40 in eastern Grey Highlands to complete two culvert replacement projects.
The road will be closed between Grey Road 7 and Grey Road 13 for about five weeks.
The county says two culverts were significantly damaged during a major summer storm in 2025. Temporary repairs were completed at that time, but continued heavy rainfall and spring runoff further eroded the embankment and weakened the structures, leaving one culvert in very poor condition.
The County says without replacement, there is a risk of failure.
To prevent repeat disruption, Grey County is replacing both culverts as part of a single project, minimizing the need for multiple road closures.
