The Southern Steel Valley is the area of post-industrial and industrial concentration along the upper Ohio River valley as well as the Monongahela River all the way to the West Virginia border. It has also included most of the Allegheny River, Beaver River and Youghiogheny River valleys. Most of the Pittsburgh metro area is considered part of "Steel Valley", as well as most of the Weirton-Steubenville-Wheeling Ohio/West Virginia, Morgantown/Fairmont West Virginia and East Liverpool/Youngstown/Mercer/New Castle Ohio and Pennsylvania metro areas. To locals in these regions the "Steel Valley" refers to towns and cities along the river shore, the school district and valley areas and not always the suburbs and cities at higher elevations, though the term has been used for the entire region. The Youngstown area of Ohio (as well as the Wheeling/Steubenville/Weirton area) though geographically and demographically connected to the "Steel Valley" retain many distinctions from the Steel Valley centered in Pittsburgh.

Acrisure Stadium is a football stadium located in the North Shore neighborhood of Pittsburgh, Pennsylvania, United States. It primarily serves as the home of the Pittsburgh Steelers of the National Football League (NFL) and the Pittsburgh Panthers of the NCAA Football in the Atlantic Coast Conference (ACC). The stadium opened in 2001, after the controlled implosion of the teams' previous home, Three Rivers Stadium, and was originally named Heinz Field because the once locally based H. J. Heinz Company purchased the naming rights in 2001. Heinz declined to sign a new deal after its naming rights expired in February 2022. Funded in conjunction with PNC Park and the David L. Lawrence Convention Center, the $281 million (equivalent to $430.03 million in 2021) stadium stands along the Ohio River, on the North Side of Pittsburgh in the North Shore neighborhood. The stadium was designed with the city of Pittsburgh's history of steel production in mind, which led to the inclusion of 12,000 tons of steel into construction. Ground for the stadium was broken in June 1999, and the first football game was hosted in September 2001. The stadium's natural-grass surface has been criticized throughout its history, but Steelers owners have kept the grass after lobbying from players and coaches. The 68,400-seat stadium has sold out for every Steelers home game, a streak that dates to 1972. A collection of Steelers and Panthers memorabilia is in the Great Hall. The stadium has hosted two outdoor hockey games: the 2011 NHL Winter Classic between the Pittsburgh Penguins and Washington Capitals, and the 2017 NHL Stadium Series game between the Penguins and Philadelphia Flyers. The venue has also hosted numerous concerts; on May 18, 2019, a Garth Brooks performance was attended by 75,000 people, the highest-ticketed show in Pittsburgh history.

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. The bridge was built from 1930 to 1932 primarily by the American Bridge Company (superstructure) and the Foundation Company (substructure). It was the longest tied-arch bridge in the world when completed, and just the second bridge to use tied-arch technology over a long span, after the Tacony–Palmyra Bridge (1929) in Philadelphia. The bridge was placed on the National Register of Historic Places in 1979 and the List of Pittsburgh History and Landmarks Foundation Historic Landmarks in 2001. As of 2016, the bridge and its surrounding approaches are undergoing some major reconstruction. The Riverlife Task Force conducted a competition in the spring of 2006 to design a pedestrian bridge across the Ohio attached to the West End Bridge. The goal of the competition was to create an iconic architectural element which ties both shore neighborhoods with the waterfronts while eliminating the need for pedestrians to cross traffic lanes and empty lots. The winning design was submitted by Endres Ware (now Endrestudio) in association with OLIN, Ammann & Whitney, Auerbach Glasow, and RWDI.

Emmanuel Episcopal Church, Pittsburgh, is an active parish of the Episcopal Diocese of Pittsburgh. It is known for offering a Sunday evening service of Jazz Vespers. Its 1886 church building is known for its architectural features and was one of the last designs by Henry Hobson Richardson. It was declared a National Historic Landmark in 2000.Though brick was selected for reasons of economy, the brickwork is one of the church's most striking features. Unlike most of Richardson's buildings, Emmanuel Episcopal's wall surfaces have fairly plain surfaces. They do not have a rough surface, moldings, belt courses or other projections to break up the planes or produce shadow lines, though the bricks do project from the main wall surface just below the eave line in two steps of different dimension to give a pleasing string course effect. Stone is used only as sills for the windows, and springing from the three entrance arches and where the foundation is exposed. This simplicity is relieved, in part, by patterning the brickwork. Of particular note, the repetitive triangular pattern at the roofline is called “mousetooth.” The brick patterning gives the impression of finely woven fabric. The sharply incised windows and doors produce dramatic voids. One of the best known features of Emmanuel Episcopal Church is a mistake. The lower section of the side wall is intended to slope inward as it rises (this is called battering). The upper wall outward slope started to take place shortly after construction. Richardson died a month after the church's dedication so his former employees, Longfellow, Alden & Harlow, were hired but they were unsuccessful in pinpointing the cause. However, when the firm added the parish house to the far side of the church, the slope stopped increasing. The building's is located at 957 West North Avenue, Pittsburgh, Pennsylvania at the corner of Allegheny Avenue on the North Side of Pittsburgh. This area was part of the City of Allegheny until 1907 when it was annexed by Pittsburgh and renamed the North Side.
