This is a complete list of current bridges and other crossings of the Ohio River from the mouth at the Mississippi River at Cairo, Illinois to the confluence of the Allegheny and Monongahela Rivers at Pittsburgh, Pennsylvania.
The source of the Ohio River is at the confluence of the Allegheny River and the Monongahela River ( 40°26′31″N80°00′50″W / 40.44194°N 80.01389°W ) at Pittsburgh, Pennsylvania.
The Ohio River is a 981-mile (1,579 km) long river in the United States. It is located at the boundary of the Midwestern and Southern United States, flowing in a southwesterly direction from western Pennsylvania to its mouth on the Mississippi River at the southern tip of Illinois. It is the third largest river by discharge volume in the United States and the largest tributary by volume of the north-south flowing Mississippi River, which divides the eastern from western United States. It is also the 6th oldest river on the North American continent. The river flows through or along the border of six states, and its drainage basin includes parts of 14 states. Through its largest tributary, the Tennessee River, the basin includes several states of the southeastern U.S. It is the source of drinking water for five million people.
The National Road was the first major improved highway in the United States built by the federal government. Built between 1811 and 1837, the 620-mile (1,000 km) road connected the Potomac and Ohio Rivers and was a main transport path to the West for thousands of settlers. When improved in the 1830s, it became the second U.S. road surfaced with the macadam process pioneered by Scotsman John Loudon McAdam.
Fort Duquesne was a fort established by the French in 1754, at the confluence of the Allegheny and Monongahela rivers. It was later taken over by the British, and later the Americans, and developed as Pittsburgh in the U.S. state of Pennsylvania. Fort Duquesne was destroyed by the French before its British conquest during the Seven Years' War, known as the French and Indian War on the North American front. The British replaced it, building Fort Pitt between 1759 and 1761. The site of both forts is now occupied by Point State Park, where the outlines of the two forts have been laid in brick.
Brownsville is a borough in Fayette County, Pennsylvania, United States, first settled in 1785 as the site of a trading post a few years after the defeat of the Iroquois enabled a resumption of westward migration after the Revolutionary War. The trading post soon became a tavern and inn and was receiving emigrants heading west, as it was located above the cut bank overlooking the first ford that could be reached to those descending from the Allegheny Mountains. Brownsville is located 40 miles (64 km) south of Pittsburgh along the east bank of the Monongahela River.
Rivesville is a town and former coal town in Marion County, West Virginia, United States. The population was 830 at the 2020 census.
The Monongahela River, sometimes referred to locally as the Mon, is a 130-mile-long (210 km) river on the Allegheny Plateau in north-central West Virginia and Southwestern Pennsylvania. The river flows from the confluence of its west and east forks in north-central West Virginia northeasterly into southwestern Pennsylvania, then northerly to Pittsburgh and its confluence with the Allegheny River to form the Ohio River. The river includes a series of locks and dams that makes it navigable.
The Ohio Country, was a name used before 1787 for a region of North America west of the Appalachian Mountains north of the upper Ohio and Allegheny rivers, and extending to Lake Erie. The area encompassed present-day northwestern West Virginia, Western Pennsylvania, most of Ohio, and a wedge of southeastern Indiana.
The Unglaciated Allegheny Plateau is located in an arc around southeastern Ohio, West Virginia, into western Pennsylvania and a small portion of southwestern New York State.
The Youghiogheny River, or the Yough for short, is a 134-mile-long (216 km) tributary of the Monongahela River in the U.S. states of West Virginia, Maryland, and Pennsylvania. It drains an area on the west side of the Allegheny Mountains northward into Pennsylvania, providing a small watershed in extreme western Maryland into the tributaries of the Mississippi River. Youghiogheny is a Lenape word meaning "a stream flowing in a contrary direction".
The Ohio Company, formally known as the Ohio Company of Virginia, was a land speculation company organized for the settlement by Virginians of the Ohio Country and to trade with the Native Americans. The company had a land grant from Britain and a treaty with Indians, but France also claimed the area, and the conflict helped provoke the outbreak of the French and Indian War.
Fort Pitt was a fort built by British forces between 1759 and 1761 during the French and Indian War at the confluence of the Monongahela and Allegheny rivers, where the Ohio River is formed in western Pennsylvania. It was near the site of Fort Duquesne, a French colonial fort built in 1754 as tensions increased between Great Britain and France in both Europe and North America. The French destroyed Fort Duquesne in 1758 when they retreated under British attack.
Yohogania County was created by the new state of Virginia in 1776, in an area long disputed between Virginia and Pennsylvania. The county ceased to exist after the border dispute between the two states was resolved in the 1780s. Thus, it is sometimes referred to as a "lost county," although 1.5 million people live within the territory it once claimed, which encompasses two entire counties and parts of four others in two states.
Redstone Old Fort — or Redstone Fort or Fort Burd — on the Nemacolin Trail, was the name of the French and Indian War-era wooden fort built in 1759 by Pennsylvania militia colonel James Burd to guard the ancient Indian trail's river ford on a mound overlooking the eastern shore of the Monongahela River in what is now Fayette County, Pennsylvania near, or on the banks of Dunlap's Creek at the confluence. The site is unlikely to be the same as an earlier fort the French document as Hangard dated to 1754 and which was confusedly, likely located on the nearby stream called Redstone Creek. Red sandstones predominate the deposited rock column of the entire region.
The Pittsburgh and West Virginia Railway was a railroad in the Pittsburgh, Pennsylvania, and Wheeling, West Virginia, areas. Originally built as the Wabash Pittsburgh Terminal Railway, a Pittsburgh extension of George J. Gould's Wabash Railroad, the venture entered receivership in 1908 and the line was cut loose. An extension completed in 1931 connected it to the Western Maryland Railway at Connellsville, Pennsylvania, forming part of the Alphabet Route, a coalition of independent lines between the Northeastern United States and the Midwest. It was leased by the Norfolk and Western Railway in 1964 in conjunction with the N&W acquiring several other sections of the former Alphabet Route, but was leased to the new spinoff Wheeling and Lake Erie Railway in 1990, just months before the N&W was merged into the Norfolk Southern Railway.
The West End Bridge is a steel tied-arch bridge over the Ohio River in Pittsburgh, Pennsylvania, approximately 1 mile (1.6 km) below the confluence of the Allegheny and Monongahela Rivers. It connects the West End to the Chateau neighborhood on the North Side of Pittsburgh.
Brownsville Road is a road between Pittsburgh, at Eighteenth Street and South Avenue in Allegheny County, Pennsylvania eastwards through Mount Oliver and generally highlands situated along or near the hilltops often overlooking the Monongahela River. It has had several names over its history, and was also known at the Red Stone Road and the period it was a Plank Road managed as a toll road, the Brownsville Plank Road, or the Brownsville Turnpike, or locally, as the area grew into a city, Southern Avenue.
Lake Monongahela was a proglacial lake in western Pennsylvania, West Virginia, and Ohio. It formed during the Pre-Illinoian ice epoch when the retreat of the ice sheet northwards blocked the drainage of these valleys to the north. The lake formed south of the ice front continued to rise until it was able to breach a low divide near New Martinsville, West Virginia. The overflow was the beginning of the process which created the modern Ohio River valley.
Blair Gap, one of the gaps of the Allegheny, is a water gap along the eastern face atop the Allegheny Front escarpment. Like other gaps of the Allegheny, the slopes of Blair Gap were amenable to foot travel, pack mules, and possibly wagons allowing Amerindians, and then, after about 1778–1780 settlers, to travel west into the relatively depopulated Ohio Country decades before the railroads were born and tied the country together with steel.
Pitt Township was one of the original townships created with the formation of Allegheny County, Pennsylvania in 1788. It repeatedly diminished in size until dissolving into the city of Pittsburgh in 1868.
