"A recent analysis of the 2013
National Bridge Inventory database from the U.S. Department of
Transportation showed that nearly a quarter of a billion times a day our
cars, trucks and school buses cross America's more than 63,000
structurally compromised bridges, including more than 2,700 in
California. The most heavily traveled of these bridges are on the
interstate highway system. With one exception, all are at least 39 years
old."This is from an excerpt of a commentary about the need to repair the U.S.'s aging infrastructure. It was written by Darlene K. Gee, PE,vice president/Northern California district leader, HNTB Corp. To read the full commentary click here.
