According to sources within the California Department of Transportation (CalTrans), all corroded steel on the 80 year old Golden Gate Bridge is being replaced with painted hot-dip galvanized steel.  This is exciting news and consistent with CalTrans's desire to use HDG steel whenever and wherever they can on new bridges.  The only obstacle to building fully galvanized steel bridges is the galvanizers’ capacity, which often allows large girders to be concrete.  In case you missed it, the AGA recently published an article regarding the cost savings had the Golden Gate Bridge initially been galvanized; this decision regarding HDG replacement steel looks like a step in the right direction.
