And if you are getting the Indiana guy....I am right on the way. I shall also buy a ticket cuz you gotta play to win.

On another note we have submitted a proposal on the Ash Creek Bridge in California for the disassembly plan. And working up a restoration plan for Cascade Bridge in Iowa where Section 106 kicked in. None of the engineers in Iowa think it should be restored. They did no maintenance and then can come up with reasons to tear down and build new. Irks me and should be prosecuted for negligence...

Anyway packing lightly for a fabulous trip with bridgehunters from many states.

Iowa Bridge Bitch.....is back

Hey Mike...if you hit the big one will you swing by Indiana and pick me up too?

Sounds good to me!

These two Montana bridges, the upper chord panel points are 1/2-panel offset from the lower chord. The C&NW bridges in Iowa, like Mississippi River at Clinton, the upper and lower panel points align.

If I win the lottery first, you two gents are both invited, but we'll have to take in some of Kansas, Oklahoma, and Missouri too.

California Craig,

I might have to go pick up one of those mega-millions tickets. If I win that jack-pot I'll pick you up in the official bridge-hunter helicopter. Maybe we can stop and get Washington K.A. too, then it's off to Beaverhead River, Montana

Keep dreaming,

Oregon Mike

OK Mr Oregon Mike, a road trip would be a blast. I would love to take a looping run up through Oregon, Washington, Idaho, Montana and then turn south, Wyoming, Colorado and then back to California picking up some Utah and Nevada along the way.

I agree with the designation of triple on this bridge and another one in the region.

So, first win the lottery to cover fuel cost... then roadtrip!

I think I see a triple as well. Nathan is right, it is very hard to tell for sure with such a fuzzy street view. Maybe California Craig and I should take a trip to Montana to confirm this along with some others in Idaho.

However, it does looks similar to the triple intersection "Iron Bridge" that I posted earlier today in Spokane, WA. It may be from the same era or even possibly the same historic railroad. Our railroad experts may be able to shed some light on this aspect.

It may be triple, the Street View honestly is too blurry for me to tell for sure.

I'm going with Triple...looks pretty definite in the view I see.

Looking at the street view in different locations makes it appear to be double, triple, and quadrangular. To me, it appears to be a triple-intersection Warren, but I could certainly be mistaken on that too. It would be nice to get photo confirmation...

Looks like a lattice truss... ie more than two intersections. I am guessing its quadruple intersection, the most common type of lattice truss. Sometimes called quadrangular.

Please review the design designation. I listed this as Double intersection Warren and I would appreciate confirmation.
