President Dwight Eisenhower signed the Federal-Aid Highway Act into law on June 29, 1956, in his room at Walter Reed Army Medical Center near Washington, D.C. It was one of 27 bills he signed that day as he recovered from intestinal surgery.
There was no signing ceremony for the highway law. There were no pictures for posterity, no commemorative pens for its congressional sponsors -- just Ike and White House aides.
It was an anticlimactic birth for an interstate highway system that would profoundly alter American society: 41,000 miles of limited-access, multilane highways that would connect major U.S. cities within a decade.
The nation's largest construction project wasn't even the day's top news story. Most Americans heard more about film star Marilyn Monroe and playwright Arthur Miller marrying in upstate New York.
The $25 billion road bill had bipartisan support, but still required two years of hard wrangling to pass after Eisenhower proposed it. It was a huge victory for longtime road advocates, including automakers, dealers, and NADA.
Within six months, the December 1956 edition of NADA Magazine reported, 31 states had awarded 107 construction contracts for the new system. Federal aid provided the bulk of the funding.
