Blood, Trauma, and Biohazard Cleanup in Carnegie, PA

Carnegie is a borough in Allegheny County about five miles southwest of Pittsburgh, built along Chartiers Creek in the Pittsburgh metropolitan area.

Carnegie was incorporated on March 1, 1894, when the neighboring boroughs of Chartiers and Mansfield voted to merge and named their new town in honor of industrialist Andrew Carnegie.

Moved by the gesture, Andrew Carnegie granted the town $200,000 in 1898 to build a library, and the Andrew Carnegie Free Library & Music Hall opened in 1901; it is now listed on the National Register of Historic Places and houses the Captain Thomas Espy Post of the Grand Army of the Republic.

Carnegie had a population of 8,134 at the 2020 census, up from 7,972 in 2010, and Census QuickFacts counts 4,217 households in the borough.

The borough's neighborhoods include Rosslyn Heights, Cubbage Hill, Irishtown, Forsythe Hill, Library Hill and Old Mansfield.

Carnegie was once home to steel plants including Superior Steel and Union Electric Steel, whose closures in the 1970s hit the borough hard.

In September 2004, flooding from Hurricane Ivan devastated Carnegie's commercial district and damaged its Roman Catholic churches, but from about 2014 its Main Street rebounded with new restaurants and small businesses and became a popular Pittsburgh-area destination.

Carnegie covers only about 1.6 square miles, making it a compact, walkable mill-town borough.

Borough students attend the Carlynton School District, which also serves Crafton and Rosslyn Farms.

Baseball Hall of Famer Honus Wagner, the Pittsburgh Pirates' legendary shortstop, and Hall of Fame football coach Mike Ditka are counted among Carnegie's hometown heroes.
