Goes both ways, Sparky: congestion can be avoided and mitigated by traffic shaping.
Your solution is to make every road a highway. That would mostly work -- but is wildly expensive. It's a child's solution: gosh, just make everything bigger and faster! And if you had unlimited resources, maybe you would.
My real world solution is to install ramp meters, high-speed passing lanes, and bus lanes. This allows the existing highway to carry more people, with rules that help both the fast cars and the slow buses.
(And the slow busses.)
