For anyone that has been to Ulleung-do, they will know this will be a difficult construction project considering the topography and sea states that surround the island:
Construction has begun on an airport in Ulleung Island in North Gyeongsang Province, which will cut down travel time from Seoul from the current seven hours to just one.
A ground-breaking ceremony took place Friday attended by Ulleung Governor Kim Byeong-su and a hundred other local and central government officials.
Ulleong Island is located in the East Sea, some 120 kilometers from mainland South Korea. The Ulleong Country administrative area includes the Dokdo Islets.
Once finished, Ulleung Airport will mainly service small aircraft with fewer than 50 seats. Local authorities expect it will increase annual tourist numbers to the remote island to one million, likely boosting the number of people taking sightseeing tours to the Dokdo Islets as well.

You can read more at the link, but I am not a big fan of the airstrip because Ulleung-do is one of the few areas in Korea that is not over run with tourists due to the boat trip currently required to get there. It just seems the small coastal road that goes around the island is going to have a hard time supporting all the tourists coming in.
