The Road Commission for Oakland County (RCOC) expects to close Cooley Lake Road, from Elizabeth Lake Road to Cass Elizabeth Road, from Monday, Aug. 18, through late September, to remove and replace a culvert under the road that carries the Elizabeth Lake Canal.
Access to homes and businesses will be maintained on both sides of the road closure. The culvert is located between Lamothe Drive and Hickory Nut Drive.
The traffic detour will be: Elizabeth Lake Road to Cass Lake Road to Cass Elizabeth Road, back to Cooley Lake Road and vice versa.
The $970,000 project is funded by RCOC and includes:
- Removing the existing, failing, corrugated-metal culvert pipe with concrete headwalls and replacing it with an aluminum pipe with aluminum headwalls.
- Repaving in the vicinity of the culvert with asphalt.
- Replacing existing guardrail.
A high-friction surface treatment will be placed on the new pavement over the culvert in 2026 to add traction. During the treatment process, the road will remain open, and flaggers will direct traffic during the work.
Superior Contracting Group of Almont is the contractor for the project. This segment of Cooley Lake Road carries approximately 18,730 vehicles daily.
