Nathan Road is the main thoroughfare in Kowloon, Hong Kong, aligned south–north from Tsim Sha Tsui to Sham Shui Po. It is lined with shops and restaurants and throngs with visitors, and was known in the post–World War II years as the Golden Mile, a name that is now rarely used. It starts on the southern part of Kowloon at its junction with Salisbury Road, a few metres north of Victoria Harbour, and ends at its intersection with Boundary Street in the north. Portions of the Kwun Tong and Tsuen Wan lines run underneath Nathan Road. The total length of Nathan Road is about 3.6 km (2.2 mi).
