The bridge structures in the United States are getting older. Many of our bridges have an average age of thirty-nine years. Bridge ratingsare declining quickly, threatening driving safety.
Bridge checkups are straightforward. Every bridge in the United States needs to undergo an inspection at least once every 2 years, yet bridge inspection teams are falling behind.
As the necessity for updated bridges increases is sorely needed, bridge inspectors must handle the inevitable repairs of our current bridge structures first.
One of the most serious problems with bridge inspection is gaining access to the bridge safely. The bridge inspection equipment is designed to lift inspection crews to hard to reach areas of large bridges. Fortunately this is not the only viable snooper truck available.
Advances in bridge technology might help close the gap in the near future making bridge inspection safer, cheaper and much more thorough than ever before.
Bridges that would never be inspected before except by using unsafe road closures or expensive downtime will now go through inspection in days instead of weeks. These new technologies allow inspectors to inspect bridges without disturbing the environment or putting wildlife in danger. As the cost of bridge inspections lessens and advanced equipment is more prevalent, our bridges can be repaired to hold up well into the future.
