Innovative Techniques and Funding for Preserving the Nation's Roadways

This article discusses the pressing need for effective management techniques, materials, and funding to enhance the nation's roadway infrastructure. With over 47,000 miles of roads rated "poor" or "mediocre," the challenges include inadequate funding and maintenance strategies. It reviews historical legislation, current deficiencies, and innovative solutions such as pavement management systems, recycling materials, and user-based funding systems like congestion pricing. Emphasizing the importance of investment relative to GDP, the article emphasizes the need for public-private collaboration to ensure sustainable road management and safety.
