From the summary:
North Dakota continues to have the nation's most efficient state-owned highway system, according to Reason Foundation's 18th Annual Highway Report.

The study finds over half of all state-owned highways across the country are congested and 25 percent of bridges are deficient or functionally obsolete.

Since 1984, per-mile total disbursements on state highways have increased by 262 percent. In 2007, U.S. states spent over $109 billion on state-owned highways, a 10 percent increase over 2006. But not everyone is getting their money's worth. Taxpayers in New York, Hawaii, New Jersey, California, Rhode Island and Alaska have the worst-performing highway systems in the nation.

The Reason Foundation study examines state highway systems in 11 categories, including congestion, pavement condition, fatalities, deficient bridges and total spending. The annual report is based on information that each state reported for the year 2007.
