The 77km SDE Expressway, or Senai-Desaru Expressway, is an expressway in Johor that connects Senai in western Johor to Desaru in eastern Johor. It is the main connector from the east to the west of Johor. The expressway alignment traverses through Senai, Ulu Tiram, Layang Reservoir, Pasir Gudang and Penawar/Desaru.
The Senai-Desaru Expressway is the third east-west-oriented expressway in the Iskandar Malaysia area after the Pasir Gudang Highway and the Pontian-Johor Bahru Link of the Second Link Expressway.
With a new crossing over the Johor River, when opened on June 10, 2011, it shortened travel time from Senai to Desaru from 2.5 hours to one hour.
Overview of Senai-Desaru Expressway (SDE)
The works for this project involves the engineering and construction of 6 interchanges, 1 intersection, 4 toll plazas, 2 Rest & Service Areas and also the landmark bridge across Sg Johor.
Interchanges
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.
The Senai-Desaru Expressway is an alternative route to Desaru Beach, instead of Federal Route 3 and 92 from Johor Bahru and Singapore.
The highway has become the main access road to Desaru from North-South Expressway (PLUS) Southern Route E2 and a major road link to Senai International Airport from Kota Tinggi and eastern parts of Johor.
The 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 Raja Pemaisuri Bainun Bridge (Sungai Dinding Bridge) in Perak.
The section between Cahaya Baru and Penawar is built as a two-lane expressway (except the Sungai Johor-SDE bridge) while retaining the full access control, making the section as the first true two-lane expressway with full access control in Malaysia.
Facilities & Services
There is a water catchment area located along Sungai Layang sections near the Sultan Iskandar Reservoir. Senai-Desaru Expressway traverses through the environmentally sensitive water catchment area of Sultan Iskandar Reservoir.
