The Road Commission for Oakland County (RCOC), in partnership with West Bloomfield Township, will close Commerce Road, from Union Lake Road to Green Lake Road, from Tuesday, Sept. 2, through late September, to remove and replace a 98-year-old culvert between Green and Bloomfield lakes.
During the closure, residential and business access will be maintained east and west of the full road closure between Cedarbank and Warner drives.
The through-traffic detour is Commerce Road to Union Lake Road to Willow Road to Hiller Road, back to Commerce Road and vice versa.
RCOC has received necessary environmental permits from the Michigan Department of Environment, Great Lakes and Energy (EGLE) and the West Bloomfield Township Environmental Commission.
The project will not change existing water levels (either during or after construction), and the existing stream-bottom water-level control feature will be retained at the upstream culvert end.
The approximately $350,000 project will be paid for by RCOC and includes:
- Replacing the current 43-foot-long culvert with a 12-foot span and 8-foot height, with a 76-foot-long elliptical concrete pipe with a 6.3-foot span and a height of 4 feet.
- Burying the bottom of the new culvert eight inches to ultimately allow a natural stream bed throughout the culvert.
- Placing of stone (rip rap) around the culvert ends to prevent erosion.
- Paving with asphalt in the vicinity of the new culvert.
- Placing new guardrail and pavement markings.
Springline Excavating of Farmington Hills is the contractor for the project. This section of Commerce Road carries approximately 10,400 vehicles daily.
