Here's the "intersection" I was talking about. I think (from seeing it in action) this is the best option to eliminate intersecting traffic as much as possible. Both Almaden Expressway and Capitol E./Hillsdale Ave. are high traffic streets that don't see a lot of back-up from this intersection. It takes a lot more construction-wise to do this, but it alleviates congestion quite well. There are a lot of spots that have two routes onto the next expressway, not really sure why, but they help in traffic congestion (or lack thereof).
