One of the greater contributions to highway development was a well-publicized and promoted United States Army Transcontinental Motor Convoy in 1919. The convoy left the White House in Washington, D.C., on July 7, 1919, and met the Lincoln Highway route at Gettysburg, Pennsylvania. After two months of travel, the convoy reached San Francisco on September 6, 1919. Though bridges failed, vehicles broke and were sometimes stuck in mud, the convoy was greeted in communities across the country. The LHA used the convoy's difficulties to show the need for better main highways, building popular support for both local and federal funding. The convoy led to the passage of many county bond issues supporting highway construction.
