Macomb County approves $498,992 contract to modernize two signalized intersections

The Macomb County Board of Commissioners on a unanimous vote approved a $498,991.81 contract with Dan's Excavating Inc. to improve two intersections in Clinton Township, moving from diagonal signal spans to box spans to increase safety and functionality.

Brian Santo, the county presenter, said the project covers two intersections, at Moravian and Harrington, and is funded 100% from McDowell/general fund dollars. He told commissioners the improvements include roadside units (RSU) that enable connected-vehicle features: “Each intersection that we improve, we have what are considered RSU units, roadside units that are installed with the improvements,” Santo said. He added that the RSUs allow monitoring of intersection electronics in real time and remote retiming of signals during incidents.

Commissioners asked about the procurement process and how the vendor compared to other bids. Santo said the project went to bid with four bidders and that Dan's Excavating submitted the low bid. A commissioner pressed for the percentage difference between bids; Santo referred members to the bid list in the meeting packet. The board approved the contract following the discussion.

The motion to award the contract was made and seconded by county commissioners and carried unanimously. The county said the work aims to improve safety while enabling future vehicle communication capabilities as original-equipment manufacturers and infrastructure partners expand connected-vehicle technology.

The project proceeds under the contract terms approved by the board; staff will oversee implementation and scheduling with the contractor.
