What seems to be a comparable toll road here is the "Dulles Greenway". It's 22km (14 mi) and the maximum car toll is $4.75 at present. You're getting a bargain. ;-)

But until recently there were many tolls on the east coast that were $0.35 or so for fairly long distances - some tiny amount that probably hasn't been raised in 50 years. E.g. $9.05 max for a car to cover the 113 mile length of the Garden State Parkway in New Jersey ($0.08 per mile) - http://www.state.nj....=Start+Calculator

In general, we in the US don't pay enough to keep up our transportation infrastructure.

(Yes, it would suck to have to pay $20 in tolls every day. But if someone is driving 225 miles a day, they're spending at least that much in gas if they've got an average car - presumably their job makes up for it...)

(I haven't paid much attention to the HOT lanes on the Beltway yet because they're not operational.)
