Resumption of Air Purification System operation at East Ventilation Building of Central – Wan Chai Bypass and Island Eastern Corridor Link

     â€‹A spokesman for the Highways Department (HyD) said today (May 2) that remedial works on the Air Purification System (APS) at the East Ventilation Building (EVB) of the Central – Wan Chai Bypass and Island Eastern Corridor Link (CWB) had been completed and that the system had resumed operation today. The APS had been temporarily suspended due to damage to some ventilation fan components in late February 2019. The HyD together with the consultants, contractor and tunnel operator will continue close monitoring of the system and arrange an efficiency test for the whole APS of the CWB to ensure the smooth operation of the system.
      
     Moreover, the HyD will continue the investigation into the cause of the damage to the APS ventilation fan components at the EVB.
