Port Perry, Pennsylvania

Turtle Creek is a 21.1-mile-long (34.0 km) tributary of the Monongahela River in Allegheny and Westmoreland counties in the U.S. state of Pennsylvania. At its juncture with the Monongahela is Braddock, Pennsylvania, where the Battle of the Monongahela ("Braddock's Defeat") was fought in 1755. In the mid-19th century, the Pennsylvania Railroad laid tracks along the stream as part of its Main Line from Philadelphia to Pittsburgh.

The Union Railroad Port Perry Bridge is a truss bridge that carries the Pennsylvania Union Railroad across the Monongahela River between Duquesne, Pennsylvania and the former town site of Port Perry in North Versailles, Pennsylvania. Industrial pipelines adorn the bridge, as coke oven gas originating from U.S. Steel's Clairton Coke Works is conveyed to the company's Edgar Thomson Steel Works near the north end of the bridge for use as fuel. Union Railroad is owned and operated by Transtar, Inc., a subsidiary of U.S. Steel.

The PPR Port Perry Bridge is a truss bridge that carries the Port Perry Branch of the Norfolk Southern Railway across the Monongahela River between the Pennsylvania towns of North Versailles Township, and Duquesne. The bridge was built to serve the Pennsylvania Railroad, to provide better access to industrial sites, and to help through trains bypass downtown Pittsburgh. Today, the bridge and corresponding route serve a similar purpose and are used to allow high-level loads, especially double-stacked container cars, to avoid the narrower routes through Pittsburgh.

The Edgar Thomson Steel Works is a steel mill in the Pittsburgh area communities of Braddock and North Braddock, Pennsylvania, United States. It has been active since 1875. It is currently owned by U.S. Steel and is known as Mon Valley Works – Edgar Thomson Plant on its official website.

Braddock Locks & Dam (previously named Monongahela Locks and Dam No. 2) is one of nine navigational structures on the Monongahela River between Pittsburgh, Pennsylvania and Fairmont, West Virginia. Built and maintained by the U.S. Army Corps of Engineers, the gated dam and the lock form an upstream pool that is for 12.6 miles (20.3 km), stretching to Elizabeth, Pennsylvania.

East Pittsburgh is a borough in Allegheny County, Pennsylvania, about 11 miles (18 km) southeast of the confluence of the Monongahela and the Allegheny rivers at Pittsburgh. The population in 1900 stood at 2,883, and in 1910, at 5,615. As of the 2020 census, the borough population was 1,927, having fallen from 6,079 in 1940. George Westinghouse erected large works there which supplied equipment to the great power plants at Niagara Falls and for the elevated and rapid-transit systems of New York. Nearby, the George Westinghouse Bridge over Turtle Creek is a prominent fixture in the area, which is very near the borough of Braddock.

Steel Curtain is a steel roller coaster located at Kennywood amusement park in West Mifflin, Pennsylvania, near Pittsburgh. Manufactured by S&S – Sansei Technologies, the coaster reaches a height of 220 feet (67 m) and features nine inversions, including a 197-foot (60 m) corkscrew that is the world's tallest inversion. Themed to the Pittsburgh Steelers, the roller coaster is named after the Steel Curtain, the nickname for the Steelers' defensive line during the 1970s. Steel Curtain is located on the former site of the Log Jammer, a flume ride that closed in 2017. The current roller coaster was announced in July 2018 following a two-phase teaser campaign, Project 412, that generated publicity for the ride. The track was topped out in March 2019 and, after a series of weather-related delays, the ride opened on July 13, 2019. Steel Curtain received Amusement Today magazine's Golden Ticket Award for Best New Roller Coaster in 2019.

George Westinghouse Memorial Bridge in East Pittsburgh, Pennsylvania, carries U.S. Route 30, the Lincoln Highway, over the Turtle Creek Valley near to where it joins the Monongahela River Valley east of Pittsburgh. The reinforced concrete open-spandrel deck arch bridge has a total length of 1,598 feet (487 m) comprising five spans. The longest, central span is 460 feet (140 m), with the deck height 240 feet (73 m) above the valley floor, for a time the world's longest concrete arch span structure. It cost $1.75 million ($34.8 million in 2021 dollars). The design engineers were Vernon R. Covell and George S. Richardson, with architectural design by Stanley Roush. The pylons at the ends of the bridges feature Art Deco reliefs by Frank Vittor.The bridge is named for George Westinghouse (October 6, 1846 – March 12, 1914), the American entrepreneur and engineer. Nearby was the famous Westinghouse Electric Corporation East Pittsburgh Works, which is now an industrial park. Notable attractions visible while driving across the bridge include the Edgar Thomson Steel Works (U.S. Steel Mon Valley Works) and Kennywood Park.

The Racer is a wooden racing roller coaster located at Kennywood amusement park near Pittsburgh in West Mifflin, Pennsylvania. Built by Charlie Mach and designed by the legendary John A. Miller, the Racer opened to the public in 1927 and is one of the oldest operating roller coasters in the world. It features a Möbius loop layout, in which both of its trains travel along one continuous track. Each train returns to the opposite side of the station from which it began.

Jack Rabbit is a wooden roller coaster located at Kennywood Park near Pittsburgh in West Mifflin, Pennsylvania. Designed and built by John A. Miller and Harry C. Baker, Jack Rabbit opened in 1920, making it one of the oldest roller coasters in the world still in operation. The ride's three trains were manufactured by Edward Vettel, Sr. in 1951 and contain three cars of six seats each. The aging cars are considered a part of the ride's nostalgic experience but also lead to some young children being disallowed to enter the ride (42” is the minimum), due to the use of a small lap bar to hold in riders. A popular early feature of the ride was a tunnel which covered the turnaround section after the first drop, but this was removed in 1947 when the new cars were ordered. In 1991, the tunnel was restored, at a slightly shorter length. The Jack Rabbit was built shortly after Miller patented a new track design in 1920 (which all wooden coasters built since have used). This design involved the use of wheels both under and over the track, which allowed Miller to create the then enormous 70-foot (21 m) drop that is the attraction's largest. It is most well known for its double dip element following the lift hill. The double dip produces strong airtime that makes the rider feel that they will be thrown from the seat, and a feeling that the train leaves the track (it rises up but the upstop wheels keep it firmly on the rails). According to Rick Sebak, producer of Pittsburgh history programs for WQED, the layout and train design results in the rear seat of each train experiencing the greatest amount of airtime.In 2019, Kennywood released a video of the Jack Rabbit, likely from 1920, on their YouTube channel. The video features clips of people on the ride and clips taken from the front row seat of the Jack Rabbit. Kennywood claims their video is "the oldest coaster POV video in the world".

Kennywood is an amusement park located in West Mifflin, Pennsylvania, just southeast of Pittsburgh. The park opened on May 30, 1899, as a trolley park attraction at the end of the Mellon family's Monongahela Street Railway. It was purchased in 1906 by F. W. Henninger and Andrew McSwigan, both of whom later formed the family-owned Kennywood Entertainment Company. The company later sold Kennywood, along with four other parks, in 2007 to Parques Reunidos, an international entertainment operator based in Spain. The amusement park features various structures and rides dating back to the early 1900s. Along with Rye Playland Park, it is one of two amusement parks in the United States designated as a National Historic Landmark. Kennywood is also one of thirteen trolley parks in the United States that remain in operation.

Thunderbolt, previously known as Pippin, is a wooden roller coaster located at Kennywood amusement park near Pittsburgh in West Mifflin, Pennsylvania. It was originally built and designed by John A. Miller and opened in 1924. It was later renovated for the 1968 season, which involved a major track expansion designed by Andy Vettel. It reopened to the public as Thunderbolt. It is partially known for being one of the few rides at Kennywood to require a partner.
