When did Allegheny City merged with Pittsburgh?
Also question is, when did the steel industry leave Pittsburgh?
Following World War II, Pittsburgh launched a clean air and civic revitalization project known as the "Renaissance." The industrial base continued to expand through the 1960s, but after 1970 foreign competition led to the collapse of the steel industry, with massive layoffs and mill closures.
Accordingly, is Deutschtown Pittsburgh Safe?
West Deutschtown is a beautiful neighborhood and has been revitalized for the most part. East Deutschtown is in ruins, but has lots of potential. Neither neighborhood is dangerous or crime-ridden. Actually, that highway was built in the 80's not the 60's, although the plans actually dated from the 50's.
Once the center of the American steel industry, and still known as "The Steel City", today the city of Pittsburgh has no steel mills within its limits, though Pittsburgh-based companies such as US Steel, Ampco Pittsburgh and Allegheny Technologies own several working mills in the Pittsburgh metropolitan area.
