Over the next three years, MDOT will install 5,700 miles of centerline rumble strips (and an additional 1,700 miles of shoulder rumble strips) on rural highways across Michigan. Although the department has received some concerns about maintenance, motorcycles, and noise, it believes that if one life is saved each year, the investment in this safety initiative is well worth it.
