A marker for the Lincoln Highway, found in Sugarhouse, Utah, a neighborhood in Salt Lake City. The Lincoln Highway was the first transcontinental highway in the United States, and the first built specifically for the automobile. The Lincoln Highway runs coast-to-coast from Times Square in New York City west to Lincoln Park in San Francisco. Its total original length upon completion in 1913 was 3,389 miles. The concrete highway marker in the picture, is one of 3,000 erected along the highway by Boy Scout troops in 1928. The highway is named after Abraham Lincoln, the 19th president of the United States. He is best known for his time in office during the Civil War, and the formal freeing of the slaves with the Emancipation Proclamation in 1863.
