Addressing Current Challenges in Bridge Infrastructure Preservation and Traffic Management

The growing challenges in bridge infrastructure preservation are critical, with over 72,500 U.S. bridges classified as structurally deficient and a staggering $65.3 billion repair estimate. This deterioration, coupled with significant growth in CMV traffic, demands effective enforcement and innovative methods to prioritize actions for repair. Emerging technologies and unconventional procedures from European countries serve as models for enhancing bridge safety and efficiency. Implementing advanced monitoring systems, such as vehicle detection and profiling, is essential for supporting infrastructure resilience.
