The two concourses C-1 and C-3 are from 1988 and are still quite modern and airy on the inside, high ceilings with light from above, moving sidewalks and new jetbridges at almost gate, and the best concessions and food offerings of any Terminal in the region.
When the Central Terminal area opened in '72/'73 only two terminals were complete, A and B. C was completed a few years later but lay empty except for a two gate stub concourse which is where C-3 is located today. That two gate stub concourse acted as EWR
's International arrivals facility until Eastern's bankruptcy in 1989 made the B-3 concourse in Terminal B available for conversion, then the two gate stub concourse at Terminal C was used by CO
domestic departures (mostly A300s). I flew out of those gates on several occasions mostly to Orlando.
PeoplExpress entered into agreement with the PA to occupy the vacant Terminal C, they also invested Millions into a renovation prior to it's opening to facilitate more of a hub operation. They tore down the two circular Concourses which were built like those at Terminals A and B and replaced them with two linear concourses which could handle twice as many flights and facilitate easy connections. CO
took over the project when they took over PeoplExpress, it opened in late '88.
If you want to see an excellent aerial photo of Terminal C during the final days of the renovation prior to CO
's occupying in 1988 check out the book "Above NY", it's a big photo book at Barnes and Noble and shows the Terminal under construction with a CO
747 in Hybrid PE
colors parked at the stub International Arrivals facility with construction finishing up in the back ground.
