MI SB0372

State transportation department bears full cost of opening, widening, and improving state trunk line highways, subject to cost-sharing requirements with cities and villages based on population.

Cities and villages with 50,000+ population bear 12.5% of highway project costs, except international border crossing projects where the state bears 100% of costs.

Cities and villages with 40,000-49,999 population bear 11.25% of costs; those with 25,000-39,999 bear 8.75%, except for international border crossing projects where state bears full cost; municipalities under 25,000 bear no cost.

State department costs include right-of-way, sidewalks, street lighting, curbing, bridges, and grade separation structures when made necessary by highway construction or reconstruction.

City or village may widen highways beyond state-prescribed width for local purposes, with the municipality bearing the entire cost of extra width minus any applicable federal highway funds.
