Tolo Highway and Fanling Highway form a major trunk road serving the north New Territories. In recent years, traffic flow at some road sections of the two highways during peak hours has approached their design capacities. Over time improvement works have been progressively carried out and widening projects have been implemented in phases in order to mitigate the congestion and cope with the anticipated increase in traffic flow in the future.
The section of Tolo Highway from Ma Liu Shui to Island House Interchange was widened to a dual 4-lane carriageway in 2003. Furthermore, the section of Tolo Highway between Island House Interchange and Tai Hang is being widened from a dual 3-lane to dual 4-lane carriageway (Stage 1).Up till now, the works have in general been progressing smoothly, and are scheduled for completion in 2014.
The works of Stage 2 is a continuation of the Stage 1 works to widen the section of Fanling Highway between Tai Hang and Wo Hop Shek Interchange to form a continuous dual 4-lane major trunk road linking Sha Tin and Fanling to serve the north New Territories.
Widening of Tolo Highway/Fanling Highway between Island House Interchange and Fanling includes the widening of Tolo Highway between Island House Interchange and Tai Hang (Stage 1) and the widening of Fanling Highway between Tai Hang and Wo Hop Shek Interchange (Stage 2).
The proposed scope of works under Stage 2 includes:
- widening of a section of Fanling Highway between Tai Hang and Wo Hop Shek Interchange of about 3 kilometres (km) long from a dual 3-lane carriageway to a dual 4-lane carriageway, with standard hard shoulders added on both directions;
- widening of a slip road of about 250 metres (m) long connecting the Jockey Club Road to Fanling Highway southbound at Wo Hop Shek;
- realignment of a section of Tai Wo Service Road West of about 1.2 km long between TaiHang and Nam Wa Po;
- realignment of a section of Tai Wo Service Road East of about 1 km long between Kiu Tau and Tong Hang Tung;
- demolition of the existing Kiu Tau Vehicular Bridge and Nam Wa Po Footbridge;
- construction of a vehicular bridge of about 400 m long at Kau Lung Hang as reprovisioning of the existing bridges mentioned in (5) above;
- demolition and reprovisioning of five existing footbridges at Tai Hang, Tai Wo, Kiu Tau, HoKa Yuen and Wo Hop Shek;
- installation of noise barriers along the roads as follows:
- vertical noise barriers of about 5.1 km long (ranging from 3 m to 8 m high); and
- single-leaf cantilever noise barriers of about 350 m long (6 m high with 3m or 4.5 m cantilever).
- provision of a traffic control and surveillance system (TCSS); and
- associated road, geotechnical, landscaping, drainage, water mains, road lighting, and electrical and mechanical (E&M) works, traffic aids and environmental mitigation measures.
Detailed design of the works has been completed. Construction works commenced in July 2013 for completion of the major works in 2018.
