The fiscal year 1991 U. S. Department of Transportation Appropriations Act provided funding for an "Interstate 66 Feasibility Study." The study is also referred to as the Transamerica Transportation Corridor Feasibility Study. This report summarizes the results of the study. For the purposes of this study, the Transamerica Transportation Corridor was defined as a transcontinental route extending from the East Coast to the West Coast. The study corridor is generally located between I-70 and I-40. It has an eastern terminus in the Commonwealth of Virginia and a western terminus in southern California. The dimensions of the corridor are roughly 4,800 km long and between 400 and 560 km wide. Within this corridor area, there is a great diversity of conditions. While there are some major communities in the corridor, it has an average of 40% fewer persons per square mile than the U.S. as a whole and is situated generally between most of the major U. S. urban areas. Topography varies considerably through the corridor. This study determined whether or not another east-west, coast-to-coast Interstate-type highway is needed and appears feasible; it also analyzed more advanced transportation systems and concepts. The four transportation alternatives examined include: 1. conventional Interstate-type highway; 2. upgraded rail; 3. super-highway and truckway; 4. very high speed fixed guideway. It was determined that the Transamerica Transportation Corridor does not meet economic feasibility criteria.
