ASTM A1010 steel seems to fit a nice niche for areas which are too wet and/or salty for weathering steel. Pricing of the steel itself is about 2.8x structural steel. However, it looks to be more like 1.5x the cost for delivered, painted girders.
With the benefit of never needing to repaint the darn thing (or perform structural repairs due to corrosion) over a 100 year design life. I've been on plenty of bridge repainting projects - lots of impact on the traveling public, lots of time and lots of money. Heck, there is a 1930s truss being painted now (plus a new deck and steel repair) for about $1,000,000 more than it would have cost to do a complete replacement of the bridge.
