Seabed tunnel gets green light

GUANGZHOU: Plans for a harbor tunnel under the South China Sea have been approved, paving the way for the construction of the Hong Kong-Zhuhai-Macau bridge.

The 6.7-km tunnel will cost 21.1 billion yuan ($3 billion) and will run 40-m below sea level so it does not interfere with shipping traffic.

Its approval means construction can begin on a 29.6km bridge that will run above the tunnel and connect three major cities in the Pearl River Delta region.
