Not exactly authoritative, but to the point.

I would not express it that way. A freeway with traffic flowing at 65 MPH
in each direction isn't usually referred to as a "130 MPH freeway".
But, the freeway, like a T1 or T3, is full duplex in that traffic in one
direction does not impede traffic in the other, and traffic can travel at
the "speed limit" in both directions simultaneously.
