Tolo Highway
Tolo Highway () is a major expressway on Route 9 in Hong Kong. It connects the new towns of Sha Tin and Tai Po in the eastern New Territories, forming part of the New Territories Circular Road. The highway, constructed in three stages between 1985 and 1987, was so named as it skirts the western edge of Tolo Harbour. Route description. The highway diverges from Tai Po Road near Sha Tin Racecourse. The following of the road, running alongside the East Rail line, was built on an embankment on the west coast of Tolo Harbour towards Yuen Chau Tsai  (Island House), which marks the eastern end of the Tai Po New Town. Construction began in March 1999 to expand the section to a dual four-lane carriageway and was finished in August 2003. The section below the campus of the Chinese University of Hong Kong has since become landlocked owing to the reclamation for the Hong Kong Science Park. The next section, long, bypasses Tai Po on the hills to its south, over Wun Yiu, Ma Wo and Pun Chun Yuen. As the alignment crosses a number of remote ravines far away from existing roads, four bridges along the  bypass had to be incrementally launched. This was the first instance of such bridge building technique being adopted in Hong Kong. Originally a dual 3-lane carriageway, this section was upgraded to a dual four-lane carriageway between August 2009 and March 2014. The speed limit for the section was temporarily reduced to from during the widening works. The road ends at Lam Kam Road Interchange, where it connects to Fanling Highway via a viaduct and interchanges with Lam Kam Road, Tai Po Road and Tai Wo Service Road West. Interchanges and Junctions. There are 6 junctions along Tolo Highway : Sha Tin Racecourse, Ma Liu Shui, Science Park, Island House, Tat Wan Road and Tai Po Tai Wo Road. !|District !|Location !|km !|Interchange name !|Exit !|Destinations !|Notes
