Hwamyeong is currently under heavy construction now. There is an entrance and exit ramp being built for the bridge spanning the adjacent river. The ramps are directly infront of Centre View and Centre View Encore apartment buildings, the same buildings that house all foreign teachers that work in Hwamyeong.
Its a nightmare. Impossible to sleep as jackhammers, and drills and smashing steel disturb this once peacefull neighborhood. From sun up to 12am or 1am there is constant drilling, hammering, slamming, beeping, dumping, heavy machine work.
Once the bridge and ramps are completed it will be just as bad as traffic noise and congestion will dominate the front and side entrance of our buildings.
My advice is to not work or live in Hwamyeong anymore.
At least check it out before you commit to living there.
