Iowa's state highway system is ranked 33rd in the nation in overall performance and efficiency, according to the Annual Highway Report released by the Reason Foundation.


That is a decline from 30th and 31st in the previous two reports. The study's rankings are based on state-reported data for 2009, the most recent year with full spending statistics available.


The report measures the condition and cost-effectiveness of state-owned roads in 11 categories, including pavement condition on urban and rural interstates, urban traffic congestion, deficient bridges, unsafe narrow lanes, traffic fatalities and total spending per mile of state roads.


The report says that Iowa ranks 26th in fatality rate, 34th in deficient bridges, 37th in urban interstate pavement in poor condition and 38th in rural interstate pavement in poor condition.
Total disbursements to Iowa roads were 23 percent below the national per-mile average.


The Iowa Department of Transportation last year identified a critical funding shortfall of $215 million per year over the next 20 years for Iowa roads.


North Dakota was the top state in the report's ranking. Kansas was No. 2, Nebraska No. 6, Missouri No. 8, Wisconsin No. 31, Illinois No. 34 and Minnesota No. 42
