Mr Tsang inspects the operation of the tunnel boring machine at the site of the Hong Kong West Drainage Tunnel which runs from Tai Hang to Cyberport. It is designed to intercept and convey surface run-off in mid-hill for discharge into the sea without passing through the low-lying areas downstream so as to alleviate the flooding problem in northern Hong Kong Island.
