Bridging the Gap

Jeter Un Pont Vers L'Avenir

In the United States, a reliable and safe bridge system has resulted from rigorous state inspections and longtime repair efforts. The majority of bridge failures can be attributed to manmade events, such as being struck by barges, or floods, earthquakes, and other natural causes. Aging bridges are of major concern, since the average bridge in the United States is 43 years old - and was built to last 50 years. The issue is explored by the authors, as is the inability of individual states to keep up with bridge maintenance. The need for a national commitment to significant transportation infrastructure investment; the need for bridge problems to be fixed in order to fix congestion problems; innovation and technology's contributions to bridge safety; and future challenges are discussed. An insert details the I-35W bridge collapse in Minneapolis.
