About The Webinar

Corrosion is one of the most often-cited problems with steel bridges. To varying degrees, corrosion affects both the appearance and structural integrity of a bridge. According to the 2015 National Bridge Inventory (NBI), there are over 180,000 steel bridge structures in the United States, which is nearly 30% of the bridge inventory. A 2001 FHWA study identified the annual direct cost of corrosion for highway bridges in the United States to be $6.43 billion to $10.15 billion.

This webinar will discuss practices for corrosion prevention of the atmospherically exposed superstructure elements of steel bridges. It will address design and maintenance of both coated and uncoated steel.  The presentation will present current practices and innovative approaches.  This discussion is based on NCHRP Synthesis 517, Corrosion Prevention for Extending the Service Life of Steel Bridges.
