Center for Extreme Load Effects on Structures

At Risk: Transportation Structures

There are more than 575,000 bridges, 5 million miles of miles of roads and railway track, thousands of ports, and thousands of airports in the United States (USGS 2004). Much of this transportation structure is aging.


Major factor in disasters

Damage to transportation structures is one of the biggest problems during a natural disaster. When bridges, tunnels, and rail lines fail, help is delayed.


Critical lifelines

Many communities are connected to other areas by a limited number of bridges and tunnels. Damage to just one bridge can spell disaster for some communities.

Damaged transportation = long-term disaster

Typical time to restore transportation facilities:

  • Ports - 2 years
  • Highway structures - 20 months
  • Rail lines - 6 months

Long-term loss of bridges, tunnels, and highways affects businesses, residents and government activities. Disabled transportation can ruin a community's economic viability.

  • difficulty getting supplies
  • higher cost of supplies
  • increased expense in shipping to market

What can communities do?

  1. Identify the critical transportation structures that serve the community.
  2. Seek state-of-the-art information regarding the structures' vulnerability.
  3. Provide resources to mitigate, or boost the structures resilience.
  4. Establish a monitoring systems.
  5. Provide instant and correct information regarding a structure's status during disasters. Establish alternate routes.
  6. Plan for quick reconstruction.

How can CELES help?

  • Provide state-of-the-art structural and soil analysis.
  • Provide visual and decision-making tools for communities to make informed decisions regarding risk and benefits.
  • Develop nondestructive testing and monitoring systems of critical structures that combines with robust wireless communication during emergencies.
  • Develop customized processes to improve structural performance during extreme events.
  • Provide communities with state-of-the-art transportation analysis for disaster planning.
