Fifteen of California’s urban centers have pavement conditions that rank among the nation’s most deteriorated, according to a recently released report. The same report found that the poor condition of California’s pothole-filled roads also puts California among the states with the highest in the nation costs for car maintenance.

TRIP, a national transportation group based in Washington D.C., issued a report today examining pavement conditions and associated vehicle operation costs nationwide. The report, Bumpy Roads Ahead: America’s Roughest Rides and Strategies to Make our Roads Smoother, can be found here. According to TRIP, poor roads cost the average California motorist $762 per year. But in some communities, such as Los Angeles and the Bay Area, the cost of poor roads is much higher, more than $1,000 per year in vehicle maintenance costs.
