Notices were erected at North Point Station for few occasions about the early closure of Exit B4 – Tsat Tsz Mui Road before the end of traffic ?
These closures were to facilitate engineers removing old chillers and install a new high-efficiency ventilation system via lifting operations to maintain a comfortable station environment
10 other stations like Sheung Wan, Sai Wan Ho and Tsing Yi also have their ventilation systems replaced before this project
