As Luke said, it is a double intersecting warren. "Double intersecting" means there are two warren patterns with overlayed with the second offset one-half the distance of the of the pattern repeat of the first.
But are you sure it's a bedstead? Clearly it has vertical end posts, but to be called a beadstead the endposts have to extend below the lower chord and function as substructure. I can't tell from the photos where the lower end of the endpost is...
This would be a double-intersection Warren.
Can anyone tell me what type of bridge this is? Putnam County, Missouri has several of this type. I can see that it is a bedstead truss; however, the descriptive text for these bridges (which are obviously all related) varies between "Bedstead double-intersection Warren" and "Lattice bedstead" types. It looks like a lattice to me, but I'd like confirmation before I go around changing them.

Nearly all of the Bedsteads I have seen that are still in use have had their legs encased in concrete. I'm sure the county officials found this as a cheap and easy way to deal with deficiencies that often occurred with them.
