The Transport Department said in an October 6 notice that temporary road closures were planned in phases from 1am on Sunday, October 11, across parts of New Territories South, Kowloon West, the West Kowloon Cultural District (WKCD) and the Central Kowloon Bypass (Yau Ma Tei Section) for the Hong Kong Cyclothon. The three main events — two rides and one road race — were to start and finish on Museum Drive in the WKCD. Roads were due to reopen in phases by around 1.15pm, subject to event progress.

During closures, 120 franchised bus routes (33 Citybus, 32 KMB, 28 cross-harbour and 27 Long Win Bus) and seven green minibus routes were to be diverted, truncated or have stops relocated. Taxi stands, private carparks and roadside parking spaces within closed roads would be suspended. The department said the Central Kowloon Bypass would be affected for the first time, with its Kowloon Bay bound tube closed from 2am and the Yau Ma Tei bound tube from 7am.

The department advised the public to plan journeys early, use public transport where possible and expect heavier congestion than on past Sundays on several routes. It said the closures would not affect vehicles from Hong Kong Island, Kowloon or the New Territories East heading to the airport and Lantau Island.
