Without a first class system of interstate highways, life in America would be far different -- it would be more risky, less prosperous, & lacking in the efficiency & comfort that Americans now enjoy & take for granted. The Dwight D. Eisenhower System of Interstate & Defense Highways, in place & celebrating its 40th anniversary, must surely be the best investment a nation ever made. Consider this: it has saved the lives of at least 187,000 people; it has prevented injuries to nearly 12 million people; it has returned more that $6 in economic productivity for each $1 it cost, & much more. Photos. Charts & tables.

This document illustrates the the development, planning and construction of the Interstate Highway System, gives highlights on how the Interstate System has affected Americans' lives and looks forward to information on how the Interstate System can be improved over the next 50 years . This document also includes a number of guest editorials and gives a state-by-state look at the individual interstates.
