Due to the geography of the town, Kuala Belait is connected by roads east towards Seria. The main highway from the Malaysian border west of Kuala Belait to Muara Town passes south of the municipality, and there exists a link road towards the Kuala Belait Highway from Kampong Mumong at Jalan Pandan Lima. The highway crosses the Belait river just south of the town via a toll bridge. It costs $3 for a normal passenger car to transit the bridge one way. A glimpse of the town, including the waterfront can be seen from the bridge. It is also possible to travel west towards Kg. Sg. Teraban (and from there to Miri) by taking a ferry across the Belait River at the Kuala Belait Wharf (see Ferry below).
