Of all the bills that President Eisenhower signed during his 8 years in office, he probably put as much of himself into the one that created the Interstate System as any other, and more than most. Unfortunately, he did not have an opportunity to celebrate the occasion with a formal ceremony. The bill was among a stack that he signed on June 29, 1956, his last day at Walter Reed Army Medical Center following surgery on June 7. He made no recorded comment, issued no statement, had no celebratory photo taken. He was said to be "highly pleased."
