The Arlington Memorial Bridge is a significant historical structure that spans the Potomac River and connects the Lincoln Memorial to the Robert E. Lee house and Arlington National Cemetery. Opened in 1932, this structure was designed with elements including granite facing, sculptures of eagles and vases, poppies and oak leaves to invoke national strength. An estimated 68,000 vehicles pass over this bridge every day. 

The Problem

The bridge required full deck replacements and an evaluation of the corrosion issues. Protecting the spandrel arches on this historic structure was a priority. The evaluation determined the continued and accelerating deterioration of the concrete deck would require a full bridge closer by 2021. The first solution considered was a complete ICCP system, but value engineering from Vector engineers provided another approach. 

 

Our Solution

We identified areas with a higher risk for corrosion and used a targeted approach. Galvashield Fusion T2 Two-Stage Anodes were inserted at the high-risk areas to mitigate future corrosion issues. Where concrete repairs were needed, we used Galvashield CC anodes around the perimeter to mitigate a ring or halo effect.

The Result

Using the targeted system, we were able to address the specific areas of need rather than the entire structure—this led to providing the same or longer service life at a significant cost saving. The Galvashield Fusion T2 and CC system are a set-it-and-forget-it solution, requiring little to no maintenance or monitoring and reducing costs moving forward.
