Although Yeongseo describes the western half of the two provinces and Gwandong describes both halves together, "Yeongdong" is used much more frequently in South Korea than either of the other two names, and may be taken loosely to refer to the entire region.
The region's name lends itself to the Yeongdong Railway Line and Yeongdong Expressway, which are major transportation corridors connecting Seoul to Gangwon.
gangwon-do (province) is mainly divided into the yeongdong (east of mountain range) and yeongseo (west of mountain range) with the taebaek mountain ranges that are developed along the east side of korean peninsula.
gangwon-do is largely divided into yeongdong on the east side of the taebaek summit, the backbone of korean peninsula, and yeongseo on the west side of that ridgeline.
ground transportation between the yeongdong and yeongseo regions is sometimes inconvenient (especially in winter), as it requires going over high mountains passes such as the daegwal-ryeong, misi-ryeong, jinbu-ryeong and hangye-ryeong.
Yeongdong is the name of the region coinciding with eastern Gangwon Province in South Korea and eastern Kangwŏn Province in North Korea.
