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.
Connellsville is a city in Fayette County, Pennsylvania, United States, 36 miles (58 km) southeast of Pittsburgh and 50 miles (80 km) away via the Youghiogheny River, a tributary of the Monongahela River. It is part of the Pittsburgh Metro Area. The population was 7,637 at the 2010 census, a decline from the figure of 9,146 tabulated in 2000.
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 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".
Downtown Pittsburgh, colloquially referred to as the Golden Triangle, and officially the Central Business District, is the urban downtown center of Pittsburgh. It is located at the confluence of the Allegheny River and the Monongahela River whose joining forms the Ohio River. The triangle is bounded by the two rivers.
The Great Allegheny Passage (GAP) is a 150-mile (240 km) rail trail between Pittsburgh, Pennsylvania and Cumberland, Maryland. Together with the C&O Canal towpath, the GAP is part of a 335 mi (539 km) route between Pittsburgh and Washington, D.C., that is popular with through hikers and cyclists.
The Pittsburgh and Lake Erie Railroad, also known as the "Little Giant", was formed on May 11, 1875. Company headquarters were located in Pittsburgh, Pennsylvania. The line connected Pittsburgh in the east with Youngstown, Ohio in the Haselton neighborhood in the west and Connellsville, Pennsylvania to the east. It did not reach Lake Erie until the formation of Conrail in 1976. The P&LE was known as the "Little Giant" since the tonnage that it moved was out of proportion to its route mileage. While it operated around one tenth of one percent of the nation's railroad miles, it hauled around one percent of its tonnage. This was largely because the P&LE served the steel mills of the greater Pittsburgh area, which consumed and shipped vast amounts of materials. It was a specialized railroad deriving much of its revenue from coal, coke, iron ore, limestone, and steel. The eventual closure of the steel mills led to the end of the P&LE as an independent line in 1992.
The Allegheny County Belt System color codes various county roads to form a unique system of routes in Allegheny County, Pennsylvania, and around the city of Pittsburgh.
The Hot Metal Bridge is a truss bridge in Pittsburgh, Pennsylvania, that crosses the Monongahela River. The bridge consists of two parallel spans on a single set of piers: the former Monongahela Connecting Railroad Bridge, built in 1887, on the upstream side and the former Hot Metal Bridge, built in 1900, on the downstream side. The Monongahela Connecting Railroad Bridge carried conventional railroad traffic, while the Hot Metal Bridge connected parts of the J&L Steel mill, carrying crucibles of molten iron from the blast furnaces in ladle transfer cars to the open hearth furnaces on the opposite bank to be converted to steel. During World War II 15% of America's steel making capacity crossed over the Hot Metal Bridge, up to 180 tons per hour. The upstream span was converted to road use after a $14.6 million restoration, and opened by Mayor Tom Murphy with a ceremony honoring former steel workers on June 23, 2000. The bridge connects 2nd Avenue at the Pittsburgh Technology Center in South Oakland with Hot Metal Street in the South Side. The downstream span reopened for pedestrian and bicycle use in late 2007 after two years of work. The Great Allegheny Passage hiker/biker trail passes over this bridge as it approaches Pittsburgh's Golden Triangle area.
Pittsburgh, surrounded by rivers and hills, has a unique transportation infrastructure that includes roads, tunnels, bridges, railroads, inclines, bike paths, and stairways. The hills and rivers form many barriers to transportation within the city.
Union Railroad is a Class III switching railroad located in Allegheny County in Western Pennsylvania. The company is owned by Transtar, Inc., which is a subsidiary of Fortress Transportation and Infrastructure Investors, after being acquired from U.S. Steel in 1988. The railroad's primary customers are the three plants of the USS Mon Valley Works, the USS Edgar Thomson Steel Works, the USS Irvin Works and the USS Clairton Works.
Carrie Furnace is a former blast furnace located along the Monongahela River in the Pittsburgh area industrial town of Swissvale, Pennsylvania, and it had formed a part of the Homestead Steel Works. The Carrie Furnaces were built in 1884 and they operated until 1982. During its peak, the site produced 1,000 to 1,250 tons of iron per day. All that is left of the site are furnaces #6 and #7, which operated from 1907 to 1978, and its hot metal bridge. The furnaces, designated a National Historic Landmark in 2006, are among the only pre-World War II 20th century blast furnaces to survive.
Three Rivers Park is a public urban waterfront park along the Allegheny, Monongahela, and Ohio Rivers in Pittsburgh, Pennsylvania.
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.
The Ohio River Trail is composed of two trails: The Ohio Water Trail and the Ohio River Greenway Trail. The Ohio River Greenway Trail (ORGT) is a proposed route that would interconnect existing trails in Maryland, Pennsylvania, Ohio and West Virginia. The proposal is spearheaded by the Ohio River Trail Council (ORTC), a volunteer-led, non-profit organization. The ORTC is an Internal Revenue Service registered 501(c)(3) not-for-profit organization which relies on corporate, foundation, government, and private grants and donations to achieve its stated mission of creating a multi-use trail along the Ohio River and its tributaries. The Council is headquartered in Monaca, Pennsylvania.
The South Shore Riverfront Park is a 3.4-acre park that stretches from 25th to 29th streets along the south banks of the Monongahela River upriver from Downtown Pittsburgh, Pennsylvania, United States. It is situated on the site of the former Jones & Laughlin Steel Mill and is adjacent to the SouthSide Works retail and residential complex.
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.
The gaps of the Allegheny, meaning gaps in the Allegheny Ridge in west-central Pennsylvania, is a series of escarpment eroding water gaps along the saddle between two higher barrier ridge-lines in the eastern face atop the Allegheny Ridge or Allegheny Front escarpment. The front extends south through Western Maryland and forms much of the border between Virginia and West Virginia, in part explaining the difference in cultures between those two post-Civil War states. While not totally impenetrable to daring and energetic travelers on foot, passing the front outside of the water gaps with even sure footed mules was nearly impossible without navigating terrain where climbing was necessary on slopes even burros would find extremely difficult.
