How are speed limits determined on county roads?
A common disperception is that the Road Commission has the authority to install speed limit signs at its discretion. Before a speed limit sign can be posted, a joint "speed study" must be conducted involving the township, the Michigan State Police and the Road Commission.
As of November 9, 2006 a new primia fascie law was adopted allowing speed limits to be set according to road type and access points. An engineering study may still be required.
What causes a pothole?
Water seeping into small cracks in the pavement freezes and thaws. The expansion cycle process causes the potholes to "grow."
What is the average cost to pave a mile of road?
It may cost up to $1.5 million to widen (reconstruct) a road from two-lanes to four lanes.
What does the Road Commission do with my property tax?
Nothing! Contrary to popular belief, no property taxes come to the Road Commission. Residents may "tax" themselves for special assessment districts. Our main revenue source comes through the purchase of gasoline and diesel.
