The American Society of Civil Engineers 2017 infrastructure report card has revealed the states in the U.S. with the worst roads. At the top of the list is DC with a shameful 93 percent of its roads classified as being in poor condition. Pothole-ridden roads aren't merely an annoyance, either. The ASCE estimates that motorists in seventh-placed Connecticut will incur annual costs of $2.4 billion as a direct result of driving on the state's 21,544 miles of road. While some states (Oregon - 8%) barely have any roads in shoddy condition, overall as a country, the USA was given a 'must do better' D grade on the latest scorecard.
