Major road links between NWNT and the urban area comprise Tuen Mun Road, Castle Peak Road, and the NT Circular Road. The rapid development of new towns in NWNT and the growth in cross-boundary traffic have placed considerable pressure on these road links. As a result, congestion is often experienced in Tuen Mun Road's Kowloon-bound carriageway and in Castle Peak Road during peak hours. Road improvements Expansion of kiosks at Lok Ma Chau Boundary Crossing is underway. The 10 additional pairs of vehicle kiosks are scheduled to be completed by end 1999.
Plans are also in hand to expand the terminal building at the boundary control point.
To cope with the increasing demand along the Tuen Mun-Tsuen Wan Corridor, the remaining works for constructing the fourth climbing lane on the Tai Lam section of Tuen Mun Road was started in late 1998 for completion in late 2000. Action is also in hand to widen sections of Castle Peak Road to dual 2-lane standard. Work is in progress for the section between Siu Lam and So Kwun Wat for completion in mid 1999. Planning and design work is in hand for the remaining section between Tsuen Wan and So Kwun Wat with a view to completing construction in phases between 2003 and 2007. While a package of traffic management measures have been implemented to reduce the congestion, the completion of Pok Oi Flyover in early 1999 has brought permanent relief to the congestion problem.
