ABSTRACT
A very old concept in transportation systems is charging users a fee for the use of a particular route or corridor. In some cases the proceeds have been used to help defray the costs of building and maintaining the system. In other cases, as occurred during the Middle Ages, local nobles demanded fees from travelers using natural transportation routes, such as rivers. This chapter will discuss the use of toll roads in the United States, with attention to the shifting degree of interest over the years and the varying use of toll roads from state to state.1
