Natrona is an unincorporated community in Harrison Township, Allegheny County in the U.S. state of Pennsylvania. It is located in Western Pennsylvania within the Pittsburgh Metropolitan Statistical Area, approximately 24 miles (39 km) northeast of Downtown Pittsburgh. Natrona is situated along the Allegheny River at Lock and Dam Four, Pools Three and Four between Brackenridge, Natrona Heights, Karns, Allegheny Township, and Lower Burrell.
The Pennsylvania Canal once passed through Natrona and nearby communities in the early- to mid-19th century.
The Pennsylvania Railroad had a train station in Natrona at Vine and Federal streets; its rail line began running through the town in the mid-19th century. Later, the Pennsylvania Railroad merged with rival New York Central Railroad in 1968 to form the Penn Central Transportation Company. The Interstate Commerce Commission required that the ailing New York, New Haven and Hartford Railroad be added in 1969. The Consolidated Rail Corporation replaced the Penn Central Transportation Company and operated freight service through Natrona from 1976 until 1999 when it was divided between two companies. The Norfolk Southern Railway then operated trains through the town. Amtrak has detoured passenger service through Natrona on occasion; its nearest station is Penn Station in Downtown Pittsburgh.
The West Penn Railways provided electric street car service to Natrona from 1906 until 1937.
Local factories, beginning with the Pennsylvania Salt Manufacturing Company's Natrona Works, also operated trains through Natrona. As of 2011, Allegheny Technologies used a track to transport materials between departments at its Allegheny Ludlum Brackenridge Works.
The community is located within the Highlands School District. Highlands High School and Highlands Middle School are located in Natrona Heights. Air pollution levels (particularly chromium) measured in Natrona area schools are among the worst in the United States.
Usage in popular culture
Also, the film Striking Distance (1993) starring Bruce Willis and Sarah Jessica Parker uses a sequence where boats jump over the dam at Natrona; the Tarentum Bridge can be seen just above the dam over Jacks Island, although the structure was added there later through editing. The bridge is officially named the George D. Stuart Bridge (part of Pennsylvania Route 366) and actually located about 2.5 miles (4.0 km) downstream spanning the river between Tarentum and New Kensington.
