Miles of Toll Roads

The vast majority of roads in the United States are freeways, in the true sense of the word, no direct fee for use is charged for traveling those roads. Only a very small number of toll roads exist in the United States, as of 2008. That number will likely grow if the trend towards the privatizing of previously public activities continues.
