Abstract:A 1999 study by the American Highway Users Alliance entitled "Unclogging America's Arteries: Prescriptions for Healthier Highways" identified the 166 worst bottlenecks in the country and evaluated the benefits of removing them. By assigning monetary values to the time and fuel savings, safety improvements, and environmental benefits already identified in "Unclogging America's Arteries," this report gives transportation officials, policy makers, and the general public a clearer understanding of the significant social and economic rewards to be reaped by improving traffic flow at key chokepoints. For each bottleneck in each metropolitan area, state and local officials must weigh the cost of improvements against the benefits to be gained once the project is complete. Savings at the remarkable levels identified in this study, and conversely, the astonishing opportunity costs of inaction, should provide ample justification to move important highway improvement projects to the forefront of the nation's transportation agenda. 2 Appendices, 60 p.
