One hundred years ago, the fastest way across the country was by train, and roads were only a way of traveling locally. The Lincoln Highway changed that when it was completed in 1913, becoming the first transcontinental road stretching from Times Square in New York City to San Francisco, California. Today, the route is celebrating its 110th anniversary of leading travelers off the major highways to appreciate the nation’s charming small towns and stunning rural landscapes.
