TennDot recognizes hot-dip galvanized (HDG) steel provides cathodic and barrier protection.
The current trend to produce a 75 to 100-year life of bridges requires HDG to maintain long corrosion free life.
With road salts and rocks hitting the rail, they knew the sacrificial coating will heal any nicks or chips. TennDot has successful experience with the quality, life-cycle cost savings and ease of specifying HDG. The current trend to produce a 75 to 100 year life of bridges requires HDG to maintain long corrosion free life.
Sustainable long life is part of the TennDOT plan for construction spending. As this was a refurbishment of a bridge that had to remain open, turn time and scheduling was critical. Now the thousands of local residents and tourists will see a new bridge that will last for decades.
