In this episode of the Concrete Logic Podcast, Seth and Dan McCoy discuss the maintenance and funding of bridges in the United States. They address questions about the responsibility of bridge maintenance, the allocation of government resources, and the challenges of maintaining bridges over time. They also compare the maintenance requirements of bridges and tunnels, highlighting the environmental factors that affect each structure. Additionally, they explore the process of replacing a bridge foundation underwater and the cost considerations involved. Takeaways Bridge maintenance in the United States is the responsibility of the state in which the bridge is located, with funding provided by the federal government. The government allocates resources to bridge maintenance, but the funding is limited and needs to be prioritized among various infrastructure projects. Bridges require more maintenance over time compared to tunnels due to their exposure to the open environment and the need to manage water and salt corrosion. Replacing a bridge foundation underwater is a complex and costly process, often involving the construction of cofferdams and temporary supports. The American Road and Transportation Builders Association's Bridge Report provides comprehensive information on bridges in the United States.
