One of the largest celebrations for the opening of a paved section of the Lincoln Highway was held at Caledonia Forest Reserve Park on October 4, 1921. The new paved section stretched from Gettysburg to Chambersburg and completed a 113-mile triangular paved auto-touring route from the state capital to Gettysburg, then to Chambersburg and back to Harrisburg. An estimated 30,000 automobiles joined the celebration. The Great Roads Jubilee Pageant was promoted as the world's largest parade showing the evolution of transportation, and it included George Washington's coach from Valley Forge. Gettysburg and Wilson colleges canceled classes so students could participate, and guests from a dozen other state highway commissions joined members of the Lincoln Highway Association on the reviewing platform. Travelers coming to Caledonia State Park from the east or west used the historic Lincoln Highway. Established in 1913 as America's first coast-to-coast highway, it stretched from New York City to San Francisco, and in Pennsylvania it is known for the most part as Route 30. At the turn of the century, few of the nearly 2.5 million miles of roads were paved, and cross-country automobile travel was poor to impossible, especially in wet weather. In 1912, Carl Fisher, founder of the Indianapolis Speedway, and Henry Joy, president of the Packard Motor Company, joined several Detroit businessmen to promote building a coast-to-coast rock highway. Fisher drew a straight line on a map from New York to San Francisco and declared he would spearhead construction of America's first transcontinental highway. Joy proposed naming it for Abraham Lincoln because he believed that was a better tribute than the memorial being planned in Washington, D.C. Officially named in 1913, the transcontinental route was completed by 1925. In 1925, the Federal Highway Administration replaced highway names with route numbers, and in 1928 Boy Scouts across the nation helped install nearly 2,700 cement markers. Today, fewer than two dozen remain in Pennsylvania.
