The airport will be closed for around 7 hours later while taxiway rehabilitation process commences and the airport authority stated that the flight will not be affected.

Air Transport Capacity Enhancement Project of Civil Aviation Authority of Nepal (CAAN) initiated the runway rehabilitation on April 1, 2019 (Chaitra 18).
The up-gradation work of the runway of TIA is being carried out from 10 PM to 8 AM every day. In order to conduct advance runway rehab, the airport is closed for 10 hours a day for the three months from April 1.
China Aero Technology International Engineering Corporation Chinese Company is in charge of the runway rehabilitation project of TIA. The agreement to rehabilitate the runway was signed on November 5, 2018 at cost of around NRs. 3.75 Billion.
For the first time in the History of TIA, the runway of airport is being upgraded completely.
TIA’s runway was built in 1975. As per the international standard, runways of international airports should be refurbished with the use of new bitumen every 10 years. TIA, however, has never done that and because of that the flight operations were affected mainly on monsoon season.
