This is how more/wider roads cause more congestion:

1) Congestion is what you get when there are lots of cars on the road. More/wider roads cause a greater number of people to think they can drive longer distances. That causes a larger number of cars to be on the road for a longer distance. More cars on the road for longer distance = more congestion.

2) More/wider roads make alternative means of transportation more difficult. The best roads for moving cars fast are the worst roads for walking or taking transit. So the more roads you have, the fewer people can use the train, bus, bike or their own feet. That means almost everyone has to drive to get almost everywhere they go, which means there are more cars on the road more often. More cars on the road more often = more congestion.

This is a basic principle of transportation planning. It is called induced demand. Every transportation planner in the country knows about it. To suggest that it doesn't exist is very much a 6th grade level of sophistication on the subject.

Sorry Drew, you are wrong.
