槟威大桥
The North-South Expressway, the main arterial highway that runs through western Peninsular Malaysia and on to Singapore, also passes through the Greater Penang Conurbation via the Sungai Petani - Butterworth - Perai - Juru - Bandar Baharu route. The expressway also branches out towards the Penang Bridge and the Second Penang Bridge, thereby providing road connections between Penang Island and the rest of Peninsular Malaysia.
