Report Lists Worst Roads in the US

— -- A new study out today has found that one in four urban roads is in poor condition and that those potholes and cracked pavements cost US drivers a little more than $1,000 a year in extra car maintenance.

The report by TRIP, a nonprofit transportation research group, examined "the condition of the nation's major urban roads" as well as other factors, including transportation funding and economic development, the group said.

Of the 25 urban areas with a population of 500,000 or more with the most major roads and highways bearing pavements in poor condition, San Franciso-Oakland, California, took top place with 74 percent of its roads giving motorists the bumpiest of rides.

Of urban areas with a population between 250,000 and 500,000, Flint, Michigan, took first place with 54 percent.
