The major thoroughfares of Saipan, particularly the primary highways of Beach Road from Garapan south to Chalan Kanoa, and Middle Road are becoming increasingly congested. Average daily traffic on Beach Road in the vicinity of Susupe exceeds 27,000 vehicle trips. To assist in handling the congestion, five traffic lights, the first in the CNMI, were installed on Beach Road and Middle Road in 1993-94 and are now operational. Additional traffic lights are expected to be added over the next two years. 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.
