Cruising down the Highway, tech question!

When cruising down the highway the engine is turning at 3,000 rpm.
The wastegate is closed so the turbo is spinning pretty good.
However, the throttle plate is semi-closed.
Does this intake backpressure slow the turbo down, which also causes exhaust backpressure while cruising?
Is the bypass valve open during highway cruising so the boosted air can go somewhere?
I was doing some thinking about this while doing my regular 350 mile drive to central NY!
