The National Road (also known as the Cumberland Road) was the first major improved highway in the United States to be built by the Federal Government. About 620 miles (1,000 km) long, the National Road connected the Potomac and Ohio Rivers and was a gateway to the West for thousands of settlers. When rebuilt in the 1830s, the Cumberland Road became the first U.S. road surfaced with the macadam process pioneered by Scotsman John Loudon McAdam.
Construction began heading west in 1811 at Cumberland, Maryland, on the Potomac River. It crossed the Allegheny Mountains and southwestern Pennsylvania, reaching Wheeling, Virginia (now West Virginia), on the Ohio River in 1818. Subsequent efforts pushed the Road across the states of Ohio and Indiana. Plans were made to continue through St. Louis, at the confluence of the Mississippi and Missouri Rivers, and to the territorial capital of Jefferson City of the Missouri Territory (previously the old Louisiana Purchase of 1803, and the later part of which became the State of Missouri), upstream on the Missouri River. After the Financial Panic of 1837 and the resulting economic depression, however, Congressional funding ran dry and construction was stopped at Vandalia, Illinois, the territorial capital of the Illinois Territory, northeast of St. Louis and the Mississippi River.
National Road, also known as Peacock Road, is located off of U.S. Route 40 between Cambridge and Old Washington, Ohio. The road was placed on the National Register on 1985-08-23.
History
The National Road was authorized by President Thomas Jefferson on March 29, 1806 and reached out to Pittsburgh, Pennsylvania. The road was later expanded to stretch to Jefferson City, Missouri. The road closely followed Zane's Trace, an earlier path, and came through the Guernsey County area around 1838.
The road currently known as Peacock Road contains original brick sections of 1918 construction. However, due to costs, parts of the road were left unpaved until World War II, when the road was used for war shipment. Local inmates were used as a cost saving method to brick up the sections. When Route 40 was diverted north of this section, the old road was unknowingly saved for posterity.
Peacock Road
Part of the National Road in Center Township retains its early twentieth-century appearance. Virtually no changes have been made since the 1920s, including the pavement; the bricks laid in 1918 remain in place. This section of the road runs approximately east-west between Old Washington and Cambridge, a distance of 5 miles (8.0 km).
