The tolled expressway is a combination of a four-lane dual carriageway (Senai–Cahaya Baru section) and a two-lane single carriageway (Cahaya Baru–Penawar section), which improves road connection between western and eastern Johor. It features a closed toll system like the North–South Expressway. It is also an alternative route to Desaru Beach, instead of Federal Routes 3 and 92 from Johor Bahru and Singapore. The highway has become the main access road to Desaru from North–South Expressway Southern Route E2 and a major road link to Senai International Airport from Kota Tinggi and eastern parts of Johor. Construction of the road included the 1.7 kilometre Sungai Johor-SDE Bridge, the longest single plane cable stayed bridge in Malaysia across Johor River, which became the longest river bridge in Malaysia after Batang Sadong Bridge in Sarawak.
