Lawrence County News September 17th 1975. In the early part of the 20th century trains belonging to the Big Four Railroad Company crossed over the Embarras River via this trestle when entering and leaving Lawrenceville. The top view of the photo below, was taken from the north bank of the stream, looking south east. As can be seen, the main span of the railroad structure was supported by metal trusses anchored on stone supports on each side of the river. On the north and left, wooden pilings held the tracks above the bottom land which was often flooded with backwaters. In the background are a water tower and old power plant that supplied electricity and filtered water for Central Illinois Public Service Company customers for a great number of years.
