The decline of the steel industry began in the 1950’s or 1960’s due to cheaper foreign products taking presidence.
This had an effect on Pittsburgh with major layoffs and lost jobs, a decline in population, and ultimately the closure of the mill.
Pittsburgh as a city now had to reinvent itself.
What followed, was closing mills, massive unemployment, community degradation, and a loss of identity as a city and community. The Hazelwood neighborhood, boasting 13,000 residents at its peak in 1960, was reduced to a mere 6,000 by 1998.
The mill shut down production and closed in 1997.
