Louisiana had the country’s 15th-highest rate of rural non-interstate traffic fatalities per 100 million miles of travel in 2009, according to a report by TRIP, a national transportation research group.

There were 2.57 fatalities on rural roads for every 100 million miles of travel, while there were 1.49 fatalities for that amount of travel on all other roads in Louisiana, according to the report.

The report, “Rural Connections: Challenges and Opportunities in America’s Heartland,” also found that 15 percent of Louisiana’s rural bridges were structurally deficient. A bridge is considered structurally deficient if there is significant deterioration of the bridge deck, supports or other major components.

Ten states had a higher percentage of structurally deficient bridges than Louisiana. Pennsylvania was the worst, with 28 percent of its rural bridges deficient.
