Every four years, the American Society of Civil Engineers releases a report card on the country's infrastructure. In 2005, the organization awarded the U.S. an overall grade of D, with only the categories of bridges, parks and recreation, rail and solid waste earning a C- or higher. The country's water systems earned the worst grades overall.
The ASCE's analysis found that Tennessee's numbers weren't much better. Vehicle travel on Tennessee's highways increased 48% from 1990 to 2003, and as a result, 32% of its major urban roads are congested. Congestion in the Nashville area costs commuters $730 per person per year in excess fuel and lost time. And driving on roads in need of repair costs Tennessee motorists $636 million a year in extra vehicle repairs and operating costs - an average of $152 per motorist.
In Tennessee, 21% of bridges are structurally deficient or functionally obsolete. The state has 147 high hazard dams and 33 state-determined deficient dams. The estimated cost to rehabilitate the most critical dams is $23.5 million.
Like the rest of the country, water is a problem in Tennessee - the drinking water infrastructure needs have been estimated at $1.4 billion over the next 20 years, and the wastewater needs are more than $604 million.
In total, the Tennessee Advisory Committee on Intergovernmental Relations 2004 Infrastructure Assessment has estimated that the state's infrastructure maintenance and improvement needs require $21.6 billion.
