Federal Route 3 is a main federal road running along the east coast of Peninsula Malaysia. The 739 kilometres (459 mi) federal highway connects Rantau Panjang (near the border with Thailand) in Kelantan until Johor Bahru in Johor. The entire FT3 highway is gazetted as a part of the Asian Highway Network route 18.
The Federal Route 3 has gained a reputation as one of the best coastal highways in Malaysia and Asia due to the scenic views along the highway, as being recognised by the National Geographic Society and Harian Metro. The Federal Route 3 is named as one of the top 10 coastal highways in Asia by the National Geographic Society, while Harian Metro recognises the FT3 highway as one of the best highways in Malaysia.
The Federal Route 3 is one of the three north-south backbone federal highways in Peninsular Malaysia; the other two are the Federal Routes 1 and 5. Generally, the Federal Route 3 runs mostly along the east coast of Peninsular Malaysia.
The FT3 highway begins as a divided highway at Johor Bahru Interchange that links with the Federal Route 1, the main trunk road of the central Peninsular Malaysia, at its first kilometer. Then at Kota Tinggi, the FT3 becomes a super two highway until Pekan. However, the FT3 is not a coastal highway yet; it is only at Mersing that the FT3 highway starts to become a coastal highway. At Pekan, the FT3 crosses the Pahang River via the Sultan Abu Bakar Bridge FT3 and proceeds to Kuantan as a divided highway.
