The existing Connaught Road Central/Harcourt Road/Gloucester Road corridor is currently operating beyond capacity, resulting in frequent traffic congestion. The “Central – Wan Chai Bypass” (CWB) aims to relieve the existing traffic congestion and to cater for the anticipated traffic growth.


The CV Division organised a technical visit to the CWB Contract No. HY/2009/18 – Central Interchange on 23 March 2013. This Contract is one of the CWB works packages, comprising the construction of a 220m long tunnel in Central outside International Finance Centre (IFC), approach roads/slip road to the CWB tunnel, widening of Rumsey Street Flyover extension, modification to the existing Rumsey Street Flyover and associated drainage and landscaping works.


Before the site visit, a presentation of the project background was given by Ir Remmy Chu (Resident Engineer – PR), Ms Paula Ng (Assistant Resident Engineer) and Ms Coby Li (Public Relations Officer). The CWB will be a 4.5km dual three lane trunk road consisting of a 3.7km tunnel structure connecting the existing Rumsey Street Flyover at Central to the Island Eastern Corridor (IEC) at North Point.  It will pass underneath the Central reclamation area, the Hong Kong Convention and Exhibition Centre, the ex-Wan Chai Public Cargo Working Area, the portal of the Cross Harbour Tunnel and the Causeway Bay Typhoon Shelter before connecting to the IEC by a viaduct.


After the presentation, Ir Nelson Chin (Resident Engineer – Civil) brought the participants to the site situated near the ferry piers and IFC in Central. The on-going site works include the construction of a 220m long tunnel box structure using cut-and-cover construction method; the approach ramp connecting to the tunnel portal; and the foundation of Rumsey Street Flyover Extension. One of the major construction challenges is to protect the existing underground utilities, serving the Central area, during the bulk excavation for the construction of the cut-and-cover tunnel. A large scale temporary steel platform spanning over the cut-and-cover tunnel excavation has been erected to safeguard the existing utilities from excessive movement and settlement. Extensive survey and monitoring instrumentation has been implemented to ensure that position, movement and settlement of the existing utilities are closely tracked. An interactive question-and-answer session was held after the site visit.


On behalf of the CV Division, we would like to express our sincere thanks to the site supervision team for their kind arrangement and presentation.
