NUS Internal Shuttle Bus B1

NUS Internal Shuttle Bus B1 operates between Kent Ridge Bus Terminal and NUS Business School (BIZ 2), passing through Central Library and University Town.

ISB B1 is a trial service starting on 9 January 2017. It supplements Internal Shuttle Bus D1 in between University Town and Central Library. During the trial, the original ISB B and UTown-Computer Centre shuttle buses will be suspended. ISB B1 and B2 were introduced in January 2017 from the merger of peak-period UT-CCE shuttle and the original ISB B. ISB B1 provides additional capacity between Central Library and University Town, which is only served by ISB D1/D2.
