How Bridge Construction Works

  • Delays in project completion

    • The US has an aging infrastructure, with many bridges approaching or exceeding their lifespan. According to the Federal Highway Administration (FHA), nearly 45% of the country's bridges are 50 years or older. This aging infrastructure not only poses safety risks but also increases maintenance costs. The estimated cost of repairing or replacing the nation's structurally deficient bridges totals around $123 billion.

    Several factors contribute to the cost of bridge construction, including:
