The National Road—formerly the Cumberland Road and later celebrated as "Main Street of America"—was the United States' first great federally financed highway and a proving ground for national‑scale internal improvements.[1]
Originating at the head of navigation on the Potomac River in Cumberland, Maryland, the 4-rod (66ft; 20m) wide engineered turnpike was authorized on March29,1806 when President Thomas Jefferson signed "An Act to regulate the laying out and making a road from Cumberland … to the State of Ohio".[2] Surveyors ran a 131-mile (211km) alignment over the Allegheny Mountains to Wheeling, Virginia, on the Ohio River by 1818, building a stone‑surfaced, cambered roadway, masonry bridges, culverts, and cast‑iron mileposts that set standards for antebellum turnpikes.[3]
Between 1825 and 1838, Congress approved successive appropriations that pushed the highway westward across Ohio, Indiana, and into Illinois. Construction gangs reached Zanesville in 1833, Columbus in 1834, the eastern outskirts of Indianapolis in 1836, Terre Haute in 1838, and the then‑capital of Vandalia, Illinois—591mi (951km) from Cumberland—by 1839, when federal contracts ceased.[4][5]
From 1806 to 1838, Congress appropriated about $6.8million for surveys, right‑of‑way acquisition, grading, stone surfacing, and masonry—an unprecedented federal outlay for transportation infrastructure. The project triggered widespread debates over the constitutional scope of "internal improvements".[6]
The operation and maintenance of completed segments were transferred to the states in stages—Maryland(1833), Pennsylvania(1836), Virginia (now West Virginia)(1838), Ohio(1849), Indiana(1849), and Illinois(1856).[7] Traffic declined with the rise of canals and railroads, but many portions were rebuilt in concrete or brick during the 1910s–1930s and incorporated into U.S. Route 40.[8]
In the 20th century, with the advent of the automobile, the National Road was connected with other historic routes to California under the title, National Old Trails Road.[9] Today, much of the alignment is followed by U.S. Route 40 (US40), with various portions bearing the Alternate U.S. Route 40 (Alt. US40) designation, or various state-road numbers (such as Maryland Route 144 for several sections between Baltimore and Cumberland). Scholars regard the National Road as a foundational step toward the modern Interstate Highway System.[10]
Marker at the start of the Cumberland National Road
Construction of the Cumberland Road (which later became part of the longer National Road) was authorized on March 29, 1806, by Congress. The new Cumberland Road would replace the wagon and foot paths of the Braddock Road for travel between the Potomac and Ohio Rivers, following roughly the same alignment until just east of Uniontown, Pennsylvania. From there, where the Braddock Road turned north towards Pittsburgh, the new National Road/Cumberland Road continued west to Wheeling, Virginia (now West Virginia), also on the Ohio River.
The contract for the construction of the first section was awarded to Henry McKinley on May 8, 1811,[13] and construction began later that year, with the road reaching Wheeling on August 1, 1818. For more than 100 years, a simple granite stone was the only marker of the road's beginning in Cumberland, Maryland. In June 2012, a monument and plaza were built in that town's Riverside Park, next to the historic original starting point.
Beyond the National Road's eastern terminus at Cumberland and toward the Atlantic coast, a series of private toll roads and turnpikes were constructed, connecting the National Road (also known as the Old National Pike) with Baltimore, then the third-largest city in the country, and a major maritime port on Chesapeake Bay. Completed in 1824, these feeder routes formed what is referred to as an eastern extension of the federal National Road.
Westward extension
The Wheeling Suspension Bridge across the Ohio River was completed in 1849 and was still in use by local traffic until its closure on September 24, 2019. The bridge is now limited to pedestrians only.
In 1849, a bridge was completed to carry the National Road across the Ohio River at Wheeling. The Wheeling Suspension Bridge, designed by Charles Ellet Jr., was at the time the world's longest bridge span at 1,010 feet (310m) from tower to tower.
Transfer to states
The Cumberland Narrows west of Cumberland, part of the realigned routing
Maintenance costs on the Cumberland Road were becoming more than Congress was willing to bear. In agreements with Maryland, Virginia, and Pennsylvania, the road was to be reconstructed and resurfaced. The section that ran over Haystack Mountain, just west of Cumberland, was abandoned and a new road was built through the Cumberland Narrows.
On April 1, 1835, the section from Wheeling to Cumberland was transferred to Maryland, Pennsylvania, and Virginia (now West Virginia). The last congressional appropriation was made May 25, 1838, and in 1840, Congress voted against completing the unfinished portion of the road, with the deciding vote being cast by Henry Clay. By that time, railroads were beginning to compete for long-distance transportation. The Baltimore and Ohio Railroad was being built west from Baltimore to Cumberland, mostly along the Potomac River, which was a more direct route than the National Road across the Allegheny Plateau of West Virginia (then Virginia) to Wheeling. Construction of the National Road stopped in 1839. Portions of the road through Indiana and Illinois remained unpaved or otherwise rudimentary and were transferred to the states.
Federal construction of the road stopped at Vandalia, Illinois, which at that time was the state's capital. Illinois officials decided not to continue construction without the federal funds because two state roads from Vandalia to the St. Louis area, today's US40 and Illinois Route 140 (known then as the Alton Road), already existed.[14]
In 1927, the National Road was designated as the eastern part of US40, which still generally follows the National Road's alignment with occasional bypasses, realignments, and newer bridges. The mostly parallel Interstate 70 (I-70) now provides a faster route for through travel without the many sharp curves, steep grades, and narrow bridges of US40 and other segments of the National Road. Heading west from Hancock in western Maryland, I-70 takes a more northerly path to connect with and follow the Pennsylvania Turnpike (also designated as I-76) across the mountains between Breezewood and New Stanton, where I-70 turns west to rejoin the National Road's route (and US40) near Washington, Pennsylvania.
The more recently constructed I-68 parallels the old road from Hancock through Cumberland west to Keyser's Ridge, Maryland, where the National Road and US40 turn northwest into Pennsylvania, but I-68 continues directly west to meet I-79 near Morgantown, West Virginia. The portion of I-68 in Maryland is designated as the National Freeway.
Another remaining National Road bridge is the Wheeling Suspension Bridge at Wheeling, West Virginia. Opened in 1849 to carry the road over the Ohio River, it was the largest suspension bridge in the world until 1851, and until 2019 was the oldest vehicular suspension bridge in the United States still in use, although it has since been closed to vehicular traffic due to repeated overweight vehicles ignoring the weight limits and damaging the bridge. A newer bridge now carries the realigned US40 and I-70 across the river nearby.
Three of the road's original toll houses are preserved:
Additionally, several Old National Pike Milestones—some well-maintained, others deteriorating, and yet others represented by modern replacements—remain intact along the route.

In general, the road climbed westwards along the Amerindian trail known as Chief Nemacolin's Path, once followed and improved by a young George Washington, then also followed by the Braddock Expedition. Using the Cumberland Narrows, its first phase of construction crossed the Allegheny Mountains entered southwestern Pennsylvania, reaching the Allegheny Plateau in Somerset County, Pennsylvania. There, travelers could turn off to Pittsburgh or continue west through Uniontown and reach navigable water, the Monongahela River, at Brownsville, Pennsylvania, which was by then a major outfitting center and riverboat-building emporium. Many settlers boarded boats there to travel down the Ohio and up the Missouri, or elsewhere on the Mississippi watershed.
By 1818, travelers could press on, still following Chief Nemacolin's trail across the ford, or taking a ferry to West Brownsville, moving through Washington County, Pennsylvania, and passing into Wheeling, Virginia (now West Virginia), 45 miles (72km) away on the Ohio River. Subsequent efforts pushed the road across the states of Ohio and Indiana and into the Illinois Territory. The western terminus of the National Road at its greatest extent was at the Kaskaskia River in Vandalia, Illinois, near the intersection of modern US51 and US40.
Today, travelers driving east from Vandalia travel along modern US40 through south-central Illinois. The National Road continued into Indiana along modern US40, passing through the cities of Terre Haute and Indianapolis. Within Indianapolis, the National Road used the original alignment of US40 along West and East Washington Street (modern US40 is now routed along I-465). East of Indianapolis, the road went through the city of Richmond before entering Ohio, where the road continued along modern US40 and passed through the northern suburbs of Dayton, Springfield, and Columbus.
West of Zanesville, Ohio, despite US40's predominantly following the original route, many segments of the original road can still be found. Between Old Washington and Morristown, the original roadbed has been overlaid by I-70. The road then continued east across the Ohio River into Wheeling in West Virginia, the original western end of the National Road when it was first paved. After running 15 miles (24km) in West Virginia, the National Road then entered Pennsylvania.
The road cut across southwestern Pennsylvania, heading southeast for about 90 miles (140km) before entering Maryland. East of Keyser's Ridge, the road used modern Alt US40 to the city of Cumberland (modern US40 is now routed along I-68). Cumberland was the original eastern terminus of the road.
In the mid-19th century[citation needed], a turnpike extension to Baltimore was approved—along what is now Maryland Route 144 from Cumberland to Hancock, US40 from Hancock to Hagerstown, Alternate US40 from Hagerstown to Frederick, and Maryland Route 144 from Frederick to Baltimore. The approval process was a hotly debated subject because of the removal of the original macadam construction that made this road famous.
Nicknamed the "Main Street of America",[16] the road's presence in towns on its route and effective access to surrounding towns attracted wealthy residents to build their houses along the road in towns such as in Richmond, Indiana,[17] and Springfield, Ohio, creating Millionaires' Rows.[18]
