Major project closes Avon, Dequindre intersection through August 2022

ROCHESTER HILLS/SHELBY TOWNSHIP — A major construction project on the Oakland-Macomb County border kicked off Nov. 1, closing sections of Avon and Dequindre roads.

The Great Lakes Water Authority and the Road Commission for Oakland County are joining forces to coordinate a series of infrastructure improvements that will be made over the next two years in the Avon Road corridor between Dequindre Road and 23 Mile Road on the border of Rochester Hills and Shelby Township.  

The projects — which will be constructed over two years — include the installation of a 96-inch GLWA water transmission main, the removal and replacement of a bridge, pedestrian safety upgrades, and the construction of two roundabouts.

“The RCOC will construct a roundabout at the Avon/Dequindre intersection and will also be replacing the Avon Road bridge over the Clinton River that is in poor condition. This work will … conclude at the end of August 2022,” said Sam Fitzer, the director of engineering for the Road Commission. “GLWA will construct a roundabout at the Avon and 23 Mile Road intersection and widen East Avon Road between these two intersections, to provide a center left turn lane. As part of both our projects, the RCOC and GLWA will also construct pedestrian facilities to connect the adjacent parks and Yates Cider Mill.”

The roundabout project, according to officials, is designed to slow traffic while increasing vehicle capacity at the Avon and Dequindre intersection by 30% to 50%, significantly reducing the likelihood of serious-injury and fatal crashes.

“The issue that vexes our residents the most is traffic, congestion and moving around our community, so the work that’s going to be done here is in direct response to that,” Rochester Hills Mayor Bryan Barnett said.

This particular section of Avon Road carries approximately 17,300 vehicles daily, according to the Road Commission. Dequindre Road north of Avon Road carries about 19,000 vehicles daily, while Dequindre south of Avon carries about 13,000 vehicles daily.

The project, Barnett explained, will effectively move traffic, eliminate dangerous left-turn head-on interactions, and add nonmotorized pathways that will provide more walkability, all while adding and being proactive about a 96-inch water main that will ensure “reliable and dependable water service and delivery for many years to come.”

Cheryl Porter, the chief operating officer for the GLWA, said the new 96-inch water transmission main is of the utmost importance.

“This will provide treated drinking water to more than a million people in Oakland, Macomb and Lapeer counties,” she explained.

But what does all this construction mean for motorists?

As of Nov. 1, crews closed Avon Road from John R to 23 Mile Road, and Dequindre Road from Hamlin Road to 23 Mile Road to begin their work.

Motorists will now have to use the detours — which for Avon Road through traffic is John R Road to Hamlin Road to Ryan Road to 23 Mile Road and back to Avon Road, and vice versa.

The detour for Dequindre Road traffic is Hamlin Road to Ryan Road to 23 Mile Road, back to Dequindre Road, and vice versa.

Although officials said access to businesses, homes and Yates Park will be maintained throughout construction, access to properties east of the bridge must come from the east.

The $8.7 million project is funded with federal, Road Commission and Rochester Hills dollars. The work will be completed in two phases, with overall project completion expected in 2023.
