ANNCR: THE NATIONAL HIGHWAY SYSTEM – Today on Congressional Moment On July 7th, 1919, the U.S. Army assembled 81 motorized vehicles and 288 men in Washington, D.C. Their mission: to drive across the country. This transcontinental convoy dealt with all the poor driving conditions of the time.... incomplete or non-existent roads of dirt or sand, unsturdy bridges, and treacherous conditions from bad weather. They arrived in San Francisco 62 days later, averaging a cross-country speed of 5 miles an hour. One volunteer observer on the arduous journey was a 29 year-old soldier named Dwight Eisenhower. Twenty years later, the Bureau of Public Roads had identified to Congress the need for a national road system to improve connections between cities and states. After World War II, Congress was able to fully address this massive undertaking. There were many concerns: states wanted assurance that the government would pay its fair share of construction costs. Rural residents thought the new highways might limit access to small communities. In 1953, Dwight Eisenhower became President. Three years later, with construction and financing approved, the Federal-Aid Highway Act of 1956 was signed into law. Creating over 35,000 miles of roadway, the Interstate Highway System was completed in 1975.
