Congressional grants paid for percent of the development of an interstate highway after world war ii. question 20 options: 10 25 50 90

You might think it too high to say 90% ... but it really was 90% of funding for the Interstate Highway system that was provided by Congressional funding.  This was a huge program signed into law during the presidency of Dwight Eisenhower.  It was considered essential to the national interest.  The Federal-Aid Highway Act passed in 1956 allocated $26 billion (in 1956 dollars!) to this monumental road-building effort.
