Castle Peak Road is the longest road in Hong Kong. Completed in 1920, it runs in the approximate shape of an arc of a semi-circle. It runs West from Tai Po Road in Sham Shui Po, New Kowloon, to Tuen Mun, then north to Yuen Long then east to Sheung Shui, in the very north of the New Territories. It is divided into 22 sections. It serves south, west and north New Territories, being one of the most distant roads in early Hong Kong.
