Located at the heart of Ashton's Main Street commercial corridor is the Ashton Post Office. The building was constructed prior to 1914 and housed a variety of storefronts, as well as the local U.S. Postal Service office. In the photo, it is on the right side, five buildings back from the foreground. The photograph illustrates the original design of the building prior to the installation of the existing non-historic siding. The Ashton Post Office was used as a Lincoln Highway Control Station. Control stations were established in existing buildings along the Lincoln Highway to provide motorists with travel information. Additionally, these stations were Odometer Control points, where drivers set their odometers to zero to determine how far they had traveled from the last checkpoint and how long until the next one before the highway was marked.
