Blainsburg, Pennsylvania

The West Brownsville Junction Bridge carries the Norfolk Southern Railway across the Monongahela River from Brownsville Township to West Brownsville in the state of Pennsylvania. The main span is a 401-foot (122 m) Pennsylvania (Petit) truss. The structure was originally designed by the Pennsylvania Railroad as a low-level connector between its mainline and Waynesburg Branch. Today, the bridge continues to serve the same purpose that it has since its inception, carrying coal trains between mines and power plants or other industrial sites.

West Brownsville is a former important transportation nexus and a present-day borough in Washington County, Pennsylvania, United States and part of the Pittsburgh metropolitan area. The population was 972 at the 2020 census. Culturally, by postal route, and socially, the community is connected to cross-river sister-city Brownsville, for the two were long joined by the Amerindian trail known as Nemacolin's Path that became a wagon road after the American Revolution, but West Brownsville is a separate municipality. Brownsville was the first point where the descent from the Appalachians could safely reach the river down the generally steep banks of the Monongahela River. Between Brownsville and West Brownsville was a shallow stretch, usable as a river ford astride a major Emigrant Trail to the various attractive regions in the Northwest Territory, the first National Road, the Cumberland Pike (Now U.S. Route 40).

Redstone Creek is a historically important widemouthed canoe and river boat-navigable brook-sized tributary stream of the Monongahela River in Fayette County, Pennsylvania. The creek is 28.4 miles (45.7 km) long, running from headwaters on Chestnut Ridge north through the city of Uniontown and reaching the Monongahela at Brownsville. Located in a 1/4-mile-wide valley with low streambanks, the site was ideal for ship building in a region geologically most often characterized by steep-plunging relatively inaccessible banks — wide enough to launch and float several large boats, and indeed steamboats after 1811, and slow-moving enough to provide good docks and parking places while craft were outfitting. Brownsville, at the mouth of Redstone Creek, was an important center for boat-building, including the manufacture of paddlewheel steamboats that traveled as far as New Orleans, and, later, the upper navigable part of the Missouri. Flatboat construction is documented at the site from 1782, and the Braddock Expedition established a supply base (blockhouse) on the stream's south bank which the French destroyed after first taking Fort Necessity in 1754. The creek hosting this important activity played a critical role in the transshipment of goods and settlers in the Mississippi Basin, as it enabled the other industries in and around Brownsville to outfit and equip the settlers headed west. Nestled in the foothills on the west side of the mountains, Brownsville was a gateway funneling settlers to the Ohio Country, the lands of the Louisiana Territory, and did so until well after 1853, when railroads reached the Missouri River at Kanesville, Iowa (one Emigrant Trails destination of the town's flatboats), the far west and the Oregon Country —for the town astride the shortest, if not the easiest, land route across the great barrier to east-west traffic presented by the Allegheny Mountains.

The Lane Bane Bridge is an American truss bridge that carries vehicular traffic across the Monongahela River between Brownsville, Pennsylvania and West Brownsville, Pennsylvania.

Christ Church is a historic Anglican church in Brownsville, Pennsylvania. Completed in 1857, the church is a contributing property to the Brownsville Northside Historic District.

Bowman's Castle, also known as Nemacolin Castle, was built in present-day Brownsville, Pennsylvania, at the western terminus of the Nemacolin's Trail on the east bank of the Monongahela river. It was built around the original trading post, which was built near the site of Fort Burd, the latter built by British colonists during the French and Indian War. Construction on the castle, including addition of a crenellated tower, continued through the Victorian era, when it was considered an engineering marvel.

The Historic Church of St. Peter is a Roman Catholic church in Brownsville, Pennsylvania, in the Diocese of Greensburg. The Historic Church of St. Peter also has a partner parish in Grindstone, Pennsylvania named St. Cecilia's Roman Catholic Church, which was built in 1931.

The oldest building is Brashear's Tavern (c. 1797), and there are five buildings that date between 1815 and 1840. The contributing sites are cemeteries associated with two of the churches, including Christ Church, the burial site of Brownsville namesake Thomas Brown. Located in the district and separately listed are the St. Peter's Church and Bowman's Castle.It was added to the National Register of Historic Places in 1993.

Brownsville Commercial Historic District is a national historic district located adjacent to the Brownsville Northside Historic District at Brownsville, Fayette County, Pennsylvania. The district includes 55 contributing buildings and two contributing structures in the central business district of Brownsville. Most of the contributing buildings are three and four-story brick commercial buildings built between 1900 and 1930, with four buildings dated to the 19th century. The oldest building is the Flatiron Building (c. 1835). Other notable buildings include the International Order of Odd Fellows Building (1876), Monongahela National Bank (1902), Second National Bank (1916), Snowdon Building (1907), Union Station (1928), Crawford Building (1908), and Borough Building (1940). The contributing structures are the separately listed Dunlap's Creek Bridge and a stone railroad tunnel (1903).It was added to the National Register of Historic Places in 1993.

Dunlap's Creek Bridge was the first arch bridge in the United States built of cast iron. It was designed by Richard Delafield and built by the United States Army Corps of Engineers. Constructed from 1836 to 1839 on the National Road in Brownsville, Pennsylvania, it remains in use today. It is listed on the National Register of Historic Places and is a National Historic Civil Engineering Landmark (1978). It is located in the Brownsville Commercial Historic District and supports Market Street, the local main thoroughfare. Due to the steep sides of the Monongahela River valley, there is only room for two short streets parallel to the river's shore and graded mild enough to be comfortable to walk before the terrain rises too steeply for business traffic.

Redstone Old Fort — or Redstone Fort or (for a short time when built) 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 (colloquially, just "the Mon") in what is now Fayette County, Pennsylvania near, or (more likely) 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.
