Downtown Pittsburgh in the context of "U.S. Steel"

The Allegheny River (/ˌælɪˈɡeɪni/ AL-ig-AY-nee; Seneca: Ohi:yo'; Unami: Alikehane) is a 325-mile-long (523 km) tributary of the Ohio River that is located in western Pennsylvania and New York in the United States. It runs from its headwaters just below the middle of Pennsylvania's northern border, northwesterly into New York, then in a zigzag southwesterly across the border and through Western Pennsylvania to join the Monongahela River at the Forks of the Ohio at Point State Park in Downtown Pittsburgh, Pennsylvania.

The Allegheny River is, by volume, the main headstream of both the Ohio and Mississippi Rivers. Historically, the Allegheny was considered to be the upper Ohio River by both Native Americans and European settlers.

Point State Park (locally known as The Point) is a Pennsylvania state park which is located on 36 acres (150,000 m) in Downtown Pittsburgh, Allegheny County, Pennsylvania, US, at the confluence of the Allegheny and Monongahela rivers, forming the Ohio River.

Built on land that was acquired via eminent domain from industrial enterprises during the 1950s, the park opened in August 1974 after construction was completed on its iconic fountain. Pittsburgh settled on the current design after rejecting an alternative plan for a Point Park Civic Center designed by Frank Lloyd Wright.

Allegheny City was a municipality that existed in the U.S. state of Pennsylvania from 1788 until it was annexed by Pittsburgh in 1907. It was located north across the Allegheny River from downtown Pittsburgh, with its southwest border formed by the Ohio River, and is known as the North Side. The city's waterfront district, along the Allegheny and Ohio rivers, became Pittsburgh's North Shore neighborhood.

The boundary of Allegheny City encompassed the modern Pittsburgh neighborhoods of Allegheny Center, Allegheny West, Brighton Heights, California-Kirkbride, Central Northside, Chateau, East Allegheny, Fineview, Manchester, Marshall-Shadeland, North Shore, Perry South, Spring Hill–City View, and Troy Hill; most of Perry North; and parts of Northview Heights and Spring Garden.
