Temporary traffic controls will be implemented on the Hong Kong-Zhuhai-Macau Bridge and surrounding areas on November 8 to facilitate the men's individual road cycling event for this year's National Games.

The road race, a unique event spanning Guangdong, Hong Kong and Macau, will see 104 athletes from 25 teams compete along a 231.8-kilometre route. Hong Kong will be represented by nine athletes.

The race begins at 9am at Zhuhai Museum. Cyclists will pass through Macau before entering Hong Kong via the mega bridge.

The Hong Kong segment, approximately 55.8 km long, will take riders along the North Lantau Highway to the Hong Kong Disneyland Resort area before returning to the bridge.

After re-entering Hengqin, the race will finish back at the Zhuhai Museum at approximately 2.30pm.

According to Yeung Tak-keung, head of the National Games Coordination Office in Hong Kong, the race is expected to be in the Hong Kong segment from about 10.20am to 11.50am.

On the day of the event, specific traffic-control measures will be enforced on the bridge.

Eastbound traffic from Zhuhai and Macau to Hong Kong will be subject to controls from 9am to 12.30pm.

Conversely, westbound traffic from Hong Kong to Zhuhai and Macau will be controlled from 7.30am to 12.30pm.

During these periods, Yeung said all vehicles are prohibited from using the bridge, and travellers are advised to use alternative land border crossings.

For those needing to cross the bridge before it closes, he said travellers and vehicles must arrive at the Hong Kong Port Passenger Clearance Building or Vehicle Clearance Plaza by 6.30am to complete all departure and border crossing procedures.

"The departure service for the bridge is expected to resume normal operations at 12.30pm, but due to the ongoing race segment in Zhuhai, shuttle buses will initially only provide limited service," Yeung said.

"Therefore, citizens are advised to pay attention and avoid travelling to Zhuhai and Macau too early.

"Additionally, during the Hong Kong segment of the race, rolling traffic controls will also be implemented on the North Lantau Highway and near the Hong Kong Disneyland Resort area.

"Due to these traffic-control arrangements, travel time from North Lantau Highway to the airport is expected to increase by about 30 minutes."

Yeung said a public viewing area for the event will be set up on the pedestrian path of Fantasy Road in Disneyland.
