Anyone building with ASTM A1010 steel? 1

[TomDOT]

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.

How old is the oldest extant bridge in A1010 ?

The oldest one I know if is in California, about 10 years old. There was a much larger one built recently in Oregon.

I'm pursuing details on both of those projects - the Oregon one is better documented.

Arcelor Mittal produces it in the USA, and has more general information as well

I was hoping someone here knows of other projects.

Hm, just heard back from FHWA. Apparently there are only 4 in the US:

1 in California
2 in Oregon
1 at the Arcelor plant in PA.

Virginia is apparently planning one.

What about similar projects in Europe?
I have see articles written by Outokumpu concerning many bridge projects.
I'll try to dig up links on them.

Also this has been revised:

Thanks, Ed. I've only been looking in the USA so far.
