荃灣新市鎮
It was built in the 1960s for the two main development projects in Hong Kong, one for the Tsuen Wan New Town, another for the Kwai Chung Container Port. The road replaces the Castle Peak Road as the main connection between Tsuen Wan and Kowloon. It hosts most public bus routes from Tsuen Wan, Kwai Chung and Tsing Yi to Kowloon and vice versa. There are about one hundred bus routes using this road.
