An efficient and safe transportation infrastructure is essential to thriving communities. This infrastructure includes roads, bridges, railways, runways and other systems that are maintained by governments and commissions. The condition or our roads is one indicator of how well the infrastructure is maintained. The Minnesota Department of Transportation's Ride Quality Index measures pavement smoothness on freeways and state highways throughout Minnesota. Smooth pavement enhances mobility, improves fuel economy and reduces the amount of money spent on vehicle repair and maintenance.
