This massive infrastructure investment had devastating effects on local economies. It blighted property and pushed access to basic amenities further out.

Across the Country the Federal and State Departments of Transportation confronting shrinking budgets and cities looking for ways to increase their revenues, it is an ideal time to offer, alternatives to the reconstruction of expressways. The alternative to the highway will be discussed, showing the cost savings, improvement of mobility, and the ability to foster lasting redevelopment. Cases studies will illustrate how cities can maximize their transportation dollars while stabilizing neighborhoods.
