Sounds of boat horns and brawling packet crews resounded for many years at this lock and 142 others on the Ohio and Erie Canal. The canal was a 308-mile water toll road built between 1825 and 1832 from Lake Erie at Cleveland to the Ohio River at Portsmouth. The early growth of Akron and Massillon was due to the canal. Railroads caused its decline and the flood of 1913 destroyed its usefulness.

This covered bridge, over Middle Run, Elkrun Township, Columbiana County, is the shortest covered bridge in the United States still standing on a once-used public highway, having a clear span of 19 feet and 3 inches. It is an example, rarely found covered, of the simplest, most basic truss design, the two-panel king post truss. It has withstood the rigors of time and traffic since the 1870s and stands in eloquent testimony of the fine craftsmanship of the early Ohio bridge builders.

In 1742, a tribe of Kickapoo requested permission from Montreal’s Governor to move to a Mascoutin village on both sides of the river here. French “Coureurs de Bois” traders named the wide floodplain “La Prairie des Mascoutins” (The Meadow of the Mascoutin). In 1764, Captain Thomas Morris explored this newly acquired British territory, and met the prophetic dreamer Chief Katapelleecy here. General Anthony Wayne’s troops victoriously returned from The Battle of Fallen Timbers in 1794 and burned “Prairie de Masque.” The Treaty of Detroit in 1807 created a hunting reservation to the east, allowing settlers to acquire the surrounding lands. Ethnic tensions climaxed in 1812, when an American Captain Logan was mortally wounded near here. The Indian Removal Act of 1830 caused the remaining tribes to move west.

This bridge, spanning Brush Creek in Brush Creek Township, Scioto County, was erected in 1874 by the Smith Bridge Company of Toledo, Ohio. Robert W. Smith was granted patents for timber trusses in 1867 and 1869, and the design for this bridge is a Smith patented truss. The supplemental arches were added in 1896. Original length of 200 feet had been shortened to its present 171 feet. This plaque has been erected to give due honor to these early timber covered bridge builders and to the men of the community who so ably assisted them.

This covered bridge in the oldest still (1962) standing in the state and the last of the “double-barreled” spans in Ohio. It was built across Seven Mile Creek on the Old Camden Road in 1829-30 by Orlistus Roberts and J.L. Campbell. Its three burr-arch trusses built of native oak and poplar with a clear span of 73 feet, support the double roadway. This plaque has been erected to give due honor to the early timber covered bridge builders of Ohio and the important spans they constructed.

This covered bridge, spanning Salt Creek in Perry Township, Muskingum County was erected in the 1870s. It is a splendid example of an Ohio covered bridge built with Warren type trusses. It is being preserved as an important illustration of the sound, fine craftsmanship of the early bridge builders of Ohio. This plaque has been erected to give these men the honor they greatly deserve.

The twelfth lock on the Hocking Canal, the Sheep Pen lock underscores Southeast Ohioans’ efforts to open their region to the world during the mid-nineteenth century. Built as a guard lock, it was intended to permit slackwater navigation of the Hocking River by regulating water depths where river and canal met. Those plans were later abandoned and the mechanism was converted to a lift lock, which raised and lowered boats as required by changes in the canal’s elevation. (Continued on other side)

Oil became a valuable resource in Ohio when significant quantities were discovered in Lima in 1885. The discovery brought an economic boom to Lima and northwest Ohio. News of the Lima oil field spread, attracting the attention of John D. Rockefeller, co-founder of Standard Oil. Against the advice of his board, Rockefeller invested heavily in Lima crude, despite its high sulfur content and foul odor. Storage tanks and pipelines for the crude sprung up rapidly. Having great faith in the ingenuity of his engineers and scientists, Rockefeller stockpiled the crude and sent Standard’s chief refining specialist, J.W. Van Dyke, to Lima to construct and manage the new Solar Refinery. Together with Herman Frasch, a German chemist, the two men perfected the technique to desulphurize the crude and turn it into quality kerosene and fuel oil.
