The Road Commission for Oakland County (RCOC), in partnership with South Lyon and Lyon Township, will host a public information meeting on Tuesday, June 24, about the planned 2026 drainage improvement and reconstruction project on Pontiac Trail/Lafayette Street, from 9 Mile Road to the CSX Railroad tracks located just north of 10 Mile Road in the two communities.
The meeting will take place from 4 p.m. to 7 p.m. at South Lyon High School’s Center for Active Adults, located at 1000 North Lafayette Street, South Lyon (enter through door 31 at the southwest corner of the building). The meeting will be an open-house format, with no formal presentation.
RCOC staff will be present to answer questions throughout the meeting. Large maps and diagrams of the planned improvements will be available for public viewing.
The approximately $11 million project will be funded with federal funds and contributions from RCOC and the City of South Lyon. The project is expected to start in the spring of 2026 and be substantially completed in the fall of the same year. The work includes:
- Reconstructing the drain system between the Yerkes Drain and Detroit Street to reduce flooding.
- Installing a storm sewer from the Yerkes Drain south to University Avenue.
- Reconstructing Pontiac Trail/Lafayette Street roadway impacted by sewer construction as well as from south of Dorothy Street to the Yerkes Drain.
- Milling (removal of existing pavement) and repaving with asphalt on sections of Pontiac Trail/Lafayette Street not impacted by sewer construction.
- Modernizing traffic signals at the Pontiac Trail/Lafayette Street intersections with Reynold Sweet Parkway, McHattie Street and 10 Mile Road/Lake Street.
- Upgrading pedestrian crosswalks throughout the project to comply with the Americans with Disabilities Act (ADA).
- Replacing curbs and gutters where needed.
- Extending the southbound right-turn lane on Pontiac Trail/Lafayette Street from north of 9 Mile Road to Princeton Drive.
During the project, northbound Pontiac Trail/Lafayette Street will be closed to traffic in the project area, while southbound Pontiac Trail/Lafayette Street will remain mostly open. There will be short-term closures of southbound Pontiac Trail/Lafayette Street, and those closures will be announced. Additionally, on-street parking will be prohibited on this section of Pontiac Trail/Lafayette Street during construction.
10 Mile Road/Lake Street will be closed at Pontiac Trail/Lafayette Street for a duration to install sewer and complete other improvements. Various side street closures, including 10 Mile Road/Lake Street, will also be required for sewer and road construction.
This section of Pontiac Trail/Lafayette Street carries approximately 20,000 vehicles daily.
Anyone wishing to attend the meeting who requires special accommodations in accordance with the provisions of the Americans with Disabilities Act (ADA) or Title VI, including those requiring language assistance, should call RCOC at 248-645-2000 and ask to be directed to the RCOC Engineering Department to submit your request.
