The sinkhole, which was reported on Monday, became bigger that it now covers a single lane of road near Servay Hypermarket Likas, not far from Kota Kinabalu.
The sinkhole appeared after a sewerage pipe burst or leaked sewerage pipes.
Officials from the Sabah Public Works Department barricaded a section of the road to prevent accidents.
Engineers are now inspecting the sinkhole.
