　　Each year，road accidents kill a million people and injure millions more.The economic costs are greatest for developing countries.Earlier this year，the United Nations called for a campaign to improve road safety.

　　One way to avoid accidents is better driving.Another is better roads and bridges.Engineers in the United States have designed ten new concrete mixtures that they think could make bridges last longer.

　　Professor Paul Tikalsky leads the experiments by a team at Pennsylvania State University.He says bridges made of concrete now last about twenty－five to thirty－five years.But he says the new mixtures might extend that to seventy－five or even one－hundred years.
