Substandard roads and bridges cost Michigan drivers approximately $7 billion per year in the cost of wasted time and fuel, additional traffic crashes and increased vehicle maintenance costs as a result of state routes that have significant deterioration, are congested or lack adequate safety features, according to a new report released May 24 by TRIP, a national transportation nonprofit research organization based in Washington, D.C. The report estimates that the average cost of inadequate roadways is $1,671 annually per driver in the Detroit metro area, $1,085 annually per driver in the Grand Rapids area, $866 annually per driver in the Lansing area, and $785 per urban driver living elsewhere in the state.
