How tough was it to give Sikkim its first ever airport

Gangtok : Flying straight to Sikkim is soon going to be a reality as the Himalayan state has got its first ever airport.
Pakyong Greenfield Airport project was unique and challenging. There were steep slopes on the project site, the region receives high rainfall and there were existing water channels along the project site.
The team at the AAI came up with innovative solutions. A 'Cut and Fill' method was used to ensure that the same material cut from the uphill side was used to fill the downhill side, eliminating waste and also reducing cost.
Environment-friendly reinforcements like Gabyon and Geo-grids were used to ensure a stable and long lasting fill reinforcement. The existing water streams were smoothly channeled under the airport with no impact on the water flow.
Pakyong Airport boasts of the highest environment-friendly retaining wall in Asia and is one of the finest engineering feats of the AAI.
