+ Tre-Gate
This section of the Valley straddles part of the Tremont neighborhood
and the Maingate industrial area. It also is very close to educational institutions within
the St. Vincent's Quadrangle and is bordered on all sides by interstate highways. Tre-Gate
has a history of industrial and business innovation and at one time was home to numerous oil
and chemical companies, including John D. Rockefeller's original Standard Oil operations and
the Grasselli Chemical Company.
