Keng Lee Road, Kampong Java Road, Cavenagh Road, Marymount Road, Sembawang Road
Thomson Road is a major trunk road linking Singapore's central business district with the northern suburban areas of the country. The road is one of the longest in Singapore, starting from Novena in the south towards MacRitchie Reservoir, before continuing northwards as Upper Thomson Road towards Yishun and Sembawang.
Thomson Road was constructed to connect the city centre to the airport and naval base at Seletar. The road was originally known as Thomson Road, after which the name was Seletar Road. This resulted in confusion as the naval and air bases, were then both known as Seletar.
In response to this, parts of the road were renamed in 1939. It was determined that the road would be called Thomson Road until the Yio Chu Kang junction, whereupon it was to become Upper Thomson Road until the Mandai Road junction. From the Mandai Road junction until the northern coast, it was named as Sembawang Road. The name Seletar Road was dropped.[2]
In 1959, the Singapore Rural Board (RB) renamed the stretch of road from the junction of Braddell and Thomson Roads to the junction of Mandai and Sembawang Roads, as Upper Thomson Road.[3]
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.
