The Highways Department submitted an environmental impact assessment report on the Lion Tunnel expansion project, proposing to build a three-lane traffic tunnel with a length of about 1.4 kilometers between the two existing pipelines in the tunnel, changing from "2+2" to "3+3".

The Deputy Director of the Major Projects Management Office of the Highways Department, Cheung Ka-leung, said in a radio program today (18th) that the Lions are experiencing heavy congestion every day. In the future, Lung Cheung Road will have an independent lane going straight into the tunnel. I believe it can avoid Waterloo Road in Kowloon Tong. There is a long queue. He also pointed out that in order to maintain the operation of the tunnel, the government will drill in the middle of the two pipes without blasting, so the construction time will be longer.

Zhang Jialiang, deputy director of the Major Projects Management Office of the Highways Department, said in Hong Kong and Taiwan's "Millennium Times" that the Lions Tunnel southbound opened in 1967 and was the first traffic tunnel in Hong Kong. It was used for water supply due to water control problems at the time, and was later changed to The northbound line was opened for traffic in 1978, and the design standards are far from today’s, requiring frequent road closures in the middle of the night for maintenance. Again, it will take longer to repair in the future.”

Zhang Jialiang also pointed out that the Lion Tunnel is used by 90,000 vehicles a day. When the "2+2" is changed to "3+3", the traffic flow can be greatly increased, which can alleviate the traffic jam situation today, and the government will expand the connecting road. , Lung Cheung Road will have an independent traffic lane going straight into the tunnel, which is believed to avoid long queues on Waterloo Road in Kowloon Tong.

Study on whether spares can be used by bicycles or pedestrians after northbound refurbishment

Zhang Jialiang continued, saying that after the reconstruction, the vehicle capacity can reach 5,400 vehicles per hour, and the traffic volume will increase by 10%. The government will add soundproof screens and soundproof covers. It is estimated that the 80 decibels recorded in the Shatin World Garden can be reduced to below 70 decibels. It will be drilled in the middle of the two pipes without blasting, and the construction time will be longer. It is expected that the construction will be from 2025 to 2029, and then the southbound will be widened. In 2033, there will be "3+3", and the northbound line will be It will be refurbished until 2034. After that, it will be used as a backup. It will be studied with relevant departments to see whether bicycles or pedestrians can enter and leave Sha Tin.

According to the Environmental Impact Assessment Report submitted by the Highways Department for the Lion Tunnel Expansion Project, it is proposed to build a three-lane traffic tunnel with a length of about 1.4 kilometers between the two existing pipelines in the tunnel to replace the existing northbound pipeline; Pipeline to three-lane carriageway tunnel.

As for the existing tunnels in the direction of Shatin, refurbishment works will be carried out, and the authorities plan to use them as emergency tunnels in the future.

The Highways Department expects that the construction works will start in the first quarter of 2025, while the completion date is tentatively set for 2034.

The authorities pointed out that the project is expected to permanently affect about 0.16 hectares of forest land and 0.17 hectares of plantation area in Lion Rock Country Park, and it is recommended to provide compensatory forest land near the construction site according to the final forest land compensation plan as mitigation.

Expansion of Shizishan Tunnel|It is expected to be completed in 2034, and it will be converted into three-lane traffic. The current northbound pipeline will be reserved for emergency use. The Shizishan Tunnel will be rebuilt and newly built. The existing southbound tunnel will be converted into three-lane two-way traffic.
