槟威大桥
现更名为敦林苍祐大道的日落洞高速公路，位于槟岛东海岸，途经市中心、槟威大桥、峇六拜工业区最后在槟城国际机场结束，是槟岛的大动脉。槟城中环公路, consisting of a number of major roads like 苏格兰路和青草巷, was also created to alleviate traffic congestion around the city centre during rush hours. Meanwhile, the city proper is also linked with the western parts of Penang Island, such as Balik Pulau, via the 跨岛联邦公路6号, a circuitous route that winds along the island's coastline.
