Legislators propose a new funding model for sound barriers to tackle Michigan highway noise pollution from highways, easing the burden on local communities.
Michigan Sound Barrier Funding Bills Aim to Reduce Highway Noise
The proposed Senate Bill 80 and House Bill 4084 would establish a dedicated state fund within the Michigan Department of Treasury, administered by the Michigan Department of Transportation (MDOT), for noise abatement projects. This fund would provide a more structured approach compared to the current process, where residents must rely on legislators to secure special allocations through the state budget.
New Bills Would Create Sustainable Sound Barrier Funding
The legislation is modeled after Minnesota’s sound wall funding system, currently the only state-level funding mechanism in the country. Traditionally, sound barriers have been financed using federal funds, but projects that don’t meet federal criteria often leave affected communities without relief. The bills aim to eliminate these obstacles by allowing both the state and local governments to apply for funding, thereby addressing long-standing concerns about road noise.
“A formal funding model for sound wall construction within MDOT is needed because the current process of residents appealing to their legislator for special allocations within the annual state budget isn’t practical or sustainable,” said Sen. Webber.
I-75 Noise Complaints Spark Legislative Action
Webber, who secured a $10 million state appropriation in 2024 to build two sound walls along Interstate 75 in Troy, stressed the importance of a consistent funding mechanism. The funding was allocated after years of complaints from residents, who reported a significant increase in noise pollution following a 2015 highway expansion project.
“It is my understanding from MDOT that federal dollars are historically used to build sound walls, but that this project would not have qualified for federal funding because the original I-75 corridor project was already completed,” Webber explained. “This legislation would fix this situation in the future and save local residents a decade of time and frustration.”
Addressing Noise Pollution Across Michigan
Rep. Robinson echoed Webber’s sentiments, emphasizing the broader impact of highway noise on communities statewide.
“This bill would allow the state and local units of government to apply for funds to build out their sound wall infrastructure. This is a commonsense solution that helps local municipalities combat the road noise that affects countless residents throughout our state,” Robinson said.
The proposed fund would prioritize projects in residential areas where sound walls are currently absent, addressing a longstanding issue for communities near major highways such as I-94, I-696, and US-23.
Residents and Local Officials Weigh In
Community advocates and local officials have welcomed the proposed legislation, arguing that it provides a fairer, more efficient way to address highway noise.
“We’ve been fighting for a sound barrier for over a decade,” said a Troy resident, whose home backs up to I-75. “This legislation finally acknowledges that road noise isn’t just an inconvenience—it’s a quality-of-life issue.”
MDOT officials have yet to formally comment on the proposed funding structure but previously acknowledged that noise complaints have risen significantly following recent highway expansion projects.
Broader Context: Sound Barrier Policies Nationwide
If passed, Michigan would become the second state with a dedicated funding mechanism for sound barriers. Minnesota has been the only state to successfully implement a similar system, and officials there report positive results in reducing noise complaints.
Other states, including Ohio and Illinois, rely exclusively on federal funding, limiting the ability of local governments to secure sound barriers unless new highway projects qualify for federal noise mitigation grants.
What’s Next for the Legislation?
Both SB 80 and HB 4084 are expected to be reviewed in the Michigan Senate and House transportation committees in the coming weeks. If approved, the bills will move to a full vote in the state legislature.
Supporters argue that creating a dedicated funding source for noise abatement projects will not only expedite relief for affected residents but also provide local governments with more flexibility to address transportation-related environmental concerns.
