Highway Access: Experiences in Indiana

The experience leading to the adoption and the use of control of access in Indiana is presented. The evolution described involves the measures considered in an effort to provide satisfactorily for the traffic on the Indiana State Highway System through the construction of bypasses and dual-lane pavements; the subsequent ribbon-type development, which eventually led to the enactment of permissive controlled access legislation; and, finally, legislation that requires that all newly constructed bypasses must be of the limited-access type. Some of the more important aspects of the legislative acts are quoted. The benefits of controlled access are enumerated as well as the conclusions that were made following a study of the experiences in Indiana.
