House Bill No. 7057 mandates the Department of Transportation (DOT) to develop and implement a funding schedule for the construction of noise barriers associated with Type II projects, which are defined as retrofit projects aimed at mitigating noise on existing highways. The DOT is required to complete this schedule by October 1, 2025, and to revise it as necessary. Additionally, the bill stipulates that the DOT must publish the funding schedule and the status of each noise barrier construction project on its website. This initiative is based on the existing priority list established in accordance with section 34 of public act 23-135.

The bill does not delete any existing legal language but introduces new provisions regarding the funding and scheduling of noise barrier projects. The estimated cost for constructing noise barriers at 37 locations is projected to exceed $320 million over a 15-20 year period, with the state expected to cover at least $83 million of this cost, while the remainder may be eligible for federal reimbursement. The ongoing fiscal impact of this bill will continue into the future, depending on the timing of the construction projects.
