Are Our Bridges Safe?

Transportation, including the road network, is a very important part of the national economy, providing necessary connections between people, business, and industries. The US Interstate Highway System was initiated by President Eisenhower in the 1950s to benefit commercial and military transportation. Its nearly 50,000 miles were largely completed in 35 years and are now part of over 4 million miles of roads across the country (Federal Highway Administration (FHWA) 2015). Bridges increase the efficiency of the road network operation and are a vital component of the nation’s transportation system and economy. Loss of a major bridge can have national impacts.
