On September 1, 1928, cement posts with bronze medallions bearing President Lincoln's profile and the Lincoln Highway's red, white, and blue emblem were erected along the Lincoln Highway from New York City to San Francisco, about one per mile, for a total of 3,000, with the help of Boy Scouts. Pennsylvania had more than 300 of these markers, but only about 20 survive. A July 16, 1919, newspaper article celebrated the completion of 18 feet of concreting along Main Street in Ligonier as part of the Lincoln Highway, saying the street would soon be open through the full length of town and give automobile drivers one of the finest mile drives on the route between Pittsburgh and Philadelphia, replacing a muddy and sometimes almost impassable street with a smooth grade from one end to the other.
