Saipan International Airport is the air gateway to the CNMI and serves as the primary airport. Terminal facilities are modern and well maintained. An air traffic control tower was constructed in 1994 and commissioned in January 1995. The Federal Aviation Administration trained local residents to become certified air traffic controllers. Tinian and Rota each have modern terminal facilities.
Tinian airport is equipped with navigational aids and can now support night flights.
Rota's airfield has a single 6,000-foot runway and is also equipped with navigational aids. Plans are now being prepared to lengthen the runway to no less than 8,000 feet with parallel taxiway to address the need of continued economic growth of Rota and Tinian. This project expands the existing berthing space of 850 feet to 2,600 linear feet including dredging of the entrance channel and turning basin. The primary commercial port in the CNMI is Charlie Dock in Saipan's harbor. The harbor and docking area are undergoing extensive renovation and the channel areas of the harbor are being dredged to a depth of minus 35 feet.
