U.S. Interstate Highway System

U.S. Interstate Highway System

Sometimes, it is important to analyse what has led to the success of previous important infrastructure projects. One such project is the US Interstate Highway System, approved by President Dwight D. Eisenhower when he signed the National Interstate and Defense Highways Act in June 1956. This massive project encompasses all 50 states and includes 47,000 miles of roadway, taking 30 yeas to be completed. Even in 2019 terms, the project costs about $540 billion to complete.

And yet, this might be the most advantageous project ever for US infrastructure. Look at the following points:

“

·      It has enriched the quality of life for virtually every American.

·      It has saved the lives of at least 187,000 people.

·      It has prevented injuries to nearly 12 million people.

·      It has returned more than $6 in economic productivity for each $1 it cost.

·      It has positioned the nation for improved international competitiveness.

·      It has permitted the cherished freedom of personal mobility to flourish.

·      It has enhanced international security.” (Publicpurpose)
