Duquesne is a former steel town on the Monongahela River just South of Pittsburgh. Duquesne was the home of Andrew Carnegie's and later US steel's Duquesne works which were a major part of those steel empires. The Duquesne works, at it's peak employed 8,000 people ( 1948 ). The mill was built in 1889 and closed in 1984. The mill was demolished not long after it's closure and efforts to turn the site into an office park have been on-going since then. One small building from the mill was saved and renovated. It's now occupied by US Steel offices.
Duquesne is just 12 miles from downtown Pittsburgh which is in the beginnings of what is hopefully an economic revival. This revival however hasn't yet impacted the cities along the Monongahela River South of Pittsburgh. The greatest concentration of steel manufacture in the Pittsburgh region was South of the city along the Monongahela River. The almost complete collapse of the steel industry in this area has been devastating to the entire river valley, both North and South of Duquesne. Duquesne's population peaked in 1930 at 21,396. Today it's population is 5,558 ( 2012 ). The populations of towns neighboring Duquesne have fallen by as much or more in some cases.
Downtown Duquesne is essentially lifeless at this point. The office park that was developed to replace the steel mill has a few new warehouses and other tenants but it does not seem to be having much of an impact on the rest of Duquesne. Mckeesport is just South of Duquesne. Braddock and Homestead are just North.
