Upper Thomson Road

Thomson Road (Chinese: 汤申路, Malay: Jalan Thomson) is a major trunk road linking Singapore's central business district with the northern suburban areas. The road is named after John Turnbull Thomson, a Scotsman who was the Government Surveyor and Chief Engineer of the Straits Settlements from 1841 to 1853 and who helped build many roads into the interior of Singapore beyond the core of the city centre in the south.

It was known to the Chinese as Chia Chui Kang, literally meaning "freshwater stream" in reference to the Kallang River which crosses the road in its upper reaches near the traditional core area of present-day Ang Mo Kio. Thus, it was also known as Ang Kio Tau, meaning "head of the red bridge", the same bridge which may have given Ang Mo Kio its name. It also had a Tamil name, Thanir Pilei Sadakku, literally meaning "water-pipe street".

The present day Thomson Road begins at a major road junction with Keng Lee Road, Kampong Java Road, Cavenagh Road and Norfolk Road, and leads northwards through the Novena residential area. It passes by Toa Payoh before continuing on as Upper Thomson Road at the junction with Braddell Road and Lornie Road. It skims along the western edge of Bishan and Ang Mo Kio, then cuts through relatively undeveloped areas until it reaches the junction with Mandai Road, where it continues northwards via Sembawang Road. It is also the site of Saint Joseph Institution International, Ministry of Youth and many more.
