HB 4084 Michigan House · 2025-2026 Regular Session

Transportation: funds; funding for sound wall projects; provide for. Amends 1951 PA 51 (MCL 247.651 - 247.675) by adding sec. 14b.

HB 4084 creates a state program to fund sound walls and other noise-reduction measures along Michigan's state trunk line highways where no such barriers currently exist. It directs the Michigan Department of Transportation (MDOT) to provide grants or loans to local road authorities for constructing or maintaining these noise barriers. The program uses a scoring system prioritizing cost-effectiveness, noise reduction for residential areas (minimum 5 decibels), existing noise levels, and benefits to schools/parks. MDOT must publicly report annual applications, approvals, and project outcomes to legislative committees.
