The Chesapeake Bay-Bridge Tunnel is one of the largest bridge-tunnels in existence. It's 17.6 miles long, and was financed by toll-backed bonds, and continues to be maintained with toll money. The point being that large infrastructure projects can be financed by the free market, provided they require the users to pay for them in the future, allowing investors to profit. Here in the DC region, demand-based pricing was used in the widening of interstate 495. It works. My favorite aspect is that buses and vehicles carrying 3 or more people can use the lanes for free, while all the assholes riding by themselves have to pay handsomely for the privilege of creating congestion at rush hour. http://en.wikipedia.org/wiki/Virginia_HOT_lanes http://en.wikipedia.org/wiki/Virginia_HOT_lanes One of the funny things about the libertarian idea of making everyone pay for road use is that technology has made it much more feasible. We don't have to use toll booths anymore. Instead just stick a transponder on the window. One of the best remedies for situations in which overuse of a public good is causing environmental problems is to make people pay to use said good.
