History The Tri-Cities Airport was the principal airport for the Endicott-Johnson City-Binghamton area from the 1930s through the early 1950s. In its early years it had a passenger terminal building, control tower, and cafe. The tower and cafe have since been demolished. The main hangar, also built during the Works Progress Administration era, has also been demolished, in 2010. The small terminal building still exists, although it has been abandoned for some years. Tri-Cities Airport was planned in 1934 and began at its commissioning in 1936 with three gravel/unpaved runways of about . In 1942 the east–west and northeast–southwest runways were paved. Runway 3-21 was long and wide, but later was lengthened in the mid-1980s to and the width was reduced to . A parallel asphalt taxiway and a few connector taxiways were added. The east–west crosswind runway 9-27 was long and wide, but was abandoned around 1969 and now is used as a taxiway along a portion of its length. An Automated Weather Observing System (AWOS-3) was installed to provide current weather information to pilots. In the flood of 2006 the AWOS was destroyed and soon replaced. In the flood of 2011 the AWOS was again destroyed. In Nov 2015 replacement was again completed, this time elevated well above the 2011 water level so as to protect the equipment from future floods.
