Transportation: funds; road investment incentive program; create. Amends 1951 PA 51 (MCL 247.651 - 247.675) by adding sec. 10q.

SB 448 creates a state-funded road investment incentive program that provides dollar-for-dollar matching grants to local road agencies (like counties and cities) for road construction, maintenance, or repair projects. Local agencies must contribute non-federal, non-state funds to match the grants, and total statewide grants are capped at 1 mill of all taxable property value in Michigan. The program requires local agencies to annually verify the sources of their matching funds, and the state transportation department must establish and publish clear application and award criteria online. This bill directly affects local governments managing public roads by providing new funding flexibility while ensuring local investment.
