Looking or advise on a Trestle Table
 

I'm thinking on building the attached trestle table and I need some advice
on constructing it. With the attached picture in mind, how would one go
about attaching the vertical part of the support to the horizontal supports?

I was thinking of using a half lap and carriage bolts to fasten them
together, but before I get to that stage, I figured I'd look for other
suggestions.

Thanks
