 The Kilometre Zero of the Federal Route 180 starts at Port Klang.At most sections, the Federal Route 180 was built under the JKR R5 road standard, allowing maximum speed limit of up to 90 km/h.The Port Klang flyover above Jalan Kem was supposed to make driving between Westport and Northport faster and more convenient, but it has instead become a danger to motorists.
