Kent County Road Commission reports strong local‑road ratings but flags aging bridges, funding squeeze

Jerry Byrne, a representative of the Kent County Road Commission, briefed the Kent County Board of Commissioners Operations & Policy Committee on the road commission’s annual report, describing the county’s road network, funding sources and priorities and warning that aging bridges will require large future investments.

Byrne told commissioners the road commission manages nearly 2,000 centerline miles (about 4,200 lane miles), maintains more than 35,000 traffic signs and employs 255 people across four complexes and six divisions. "We're responsible. Nearly 2,000 centerline miles of road," Byrne said, summarizing the scope of the system.

The presentation said the commission’s major revenue source is the Michigan Transportation Fund (MTF), funded primarily by registration fees and fuel taxes, and that Kent County does not levy a countywide road millage. Byrne noted township partnerships and a local cost‑share program account for roughly 50% of some project costs and credited township matching with helping maintain a high share of roads in good or fair condition.

Byrne highlighted performance metrics: the commission’s federally eligible roads (about 600 miles) are about 74% rated good or fair, and 72% of local roads are rated good or fair. He contrasted those figures with statewide averages and said the commission aims to spread limited dollars across all 21 townships, including lower‑population and growing areas.

The presentation also described a deliberate shift in project strategy away from full reconstruction toward surface preservation and targeted resurfacing to extend pavement life and touch more miles with constrained funding. Byrne said the commission plans about 24 miles of pavement replacement and roughly 335 lane miles of improvements this year, while noting the number of miles treated annually has declined from 430 lane miles in 2023 and 378 in 2024 because construction inflation is increasing costs.

Byrne warned bridges are the largest forthcoming cost driver: the average bridge age is 55 years, with 44 bridges built between 1920 and 1979. Ten bridges have reduced truck weight limits to extend service life. "That is our biggest concern," Byrne said, adding major bridge replacements can cost many millions of dollars and would consume funds that might otherwise pay for miles of road work.

He described recent investments, including use of American Rescue Plan Act (ARPA) funds to match township contributions, and discussed capital choices such as roundabouts — which Byrne said reduce serious injury and fatal crashes but can cost roughly $2.2 million each and require right‑of‑way purchases.

Commissioners asked about state funding prospects, the effect of construction‑cost inflation and environmental coordination. Byrne said the Act 51 formula for distributing MTF is expected to remain, but state proposals could create a separate funding pot routed to local agencies (cities, villages and road commissions), with MDOT receiving a smaller share. He said recent bidding shows construction prices moderating compared with prior years.

On environmental issues, Byrne described coordination with the county Drain Commission on projects that include infiltration structures to reduce runoff to lakes, and said the road commission has reduced salt use about 15% over the past decade through technology and training while acknowledging winter safety remains the priority.

Commissioners discussed future challenges including population growth concentrated in townships and the transition toward electric vehicles, which Byrne said will require rethinking how roads are funded. "We actually have a meeting next week with state legislators ... looking at some kind of vehicle‑miles model," Byrne said, noting privacy and political concerns around mileage‑based fees.

The presentation concluded with Byrne urging commissioners and the public to use the road commission’s website for questions and updates and thanking staff for preparation.

Ending: Commissioners thanked Byrne and the road commission staff for the briefing and for work on emergency response and routine maintenance. No formal action was taken on the road commission presentation during the meeting.
