The Piscataqua River Bridge on Interstate 95 is the key entry point to Maine from New Hampshire.

The Problem

Heavy traffic and significant road salt use had created numerous spalled areas on the deck and medians. A plan was needed to minimize traffic disruptions and provide long-term performance to the repairs required for the project.

Our Solution

Galvashield XP4 galvanic anodes were installed around the perimeter of the deck's individual patches. Nearly 20,000 lineal feet of Galvashield DAS were installed at the interface along the medians between the new concrete and the older chloride-contaminated concrete.



The Result

  • The Galvashield XP4 provided protection from the ring-anode effect for all of the patches.
  • The Galvashield DAS provided rapid installation of a protection system along the length of the medians and a very high level of protection against corrosion in these areas.
