Tuen Mun Road 3.19

Tuen Mun Road is a major expressway in Hong Kong which connects Tuen Mun with Tsuen Wan, within New Territories. It is part of Hong Kong's Route 9, which circumnavigates the New Territories. Built in 1977, it was once the major trunk route linking the northwest New Territories to urban Kowloon and is known for its frequent traffic jams and road accidents owing to its early design and heavy usage. As a result, speed limits have been enforced to 70-80km/h due to geometric constraints.AlignmentThe highway leads off Yuen Long Highway at Lam Tei Interchange, where it also interchanges with Castle Peak Road and Tsing Lun Road. The next section (considered from west to east) is a dual 3 lane road through the town centre of Tuen Mun, but this section is not a statutorily designated (limited-access) expressway.Expressway regulations apply from the junction with Wong Chu Road, where it widens to 3 lanes and climbs the hillside beside Sam Shing Hui. It then descends into So Kwun Wat, crossing the rural area on an embankment. The road then rises again before descending into Siu Lam Interchange, where it interchanges with Castle Peak Road.
