Tower Transit Bus Service 167 is a trunk route between Sembawang Interchange and Bukit Merah Interchange, passing through Canberra Link, Sembawang Road, Upper Thomson, Thomson, Newton, Orchard, Dhoby Ghaut, Connaught Drive / St Andrews Road, Shenton Way, Cantonment Road and Jalan Bukit Merah.
Service 167 is an inter-town trunk route connects housing estates around Sembawang, Yishun and Bukit Merah, and the suburban areas of Upper Thomson and Thomson, with connections to the City areas of Novena, Orchard Road, Padang and Shenton Way. Along with Service 980, it serves the full stretch of Upper Thomson Road and connects to the city, and compliments Service 196 between Bukit Merah and the Central Business District.
Demand for this route remains moderate to low throughout the day owing to the presence of duplicate routes and low-density developments along much of its route. However, peak hour demand is high especially between Sembawang and the City.
