Ampang – Kuala Lumpur Elevated Highway, AKLEH (Malay: Lebuhraya Bertingkat Ampang-Kuala Lumpur) is the first elevated highway in Malaysia. The 7.7 km (4.8 mi) elevated highway connects Ampang (Selangor) and Kuala Lumpur. This highway was built to reduce traffic jams at Jalan Ampang and make access to the city more convenient.
Motorcycles and other vehicles with 2 wheels or less were initially banned from using this highway due to safety reasons; however, the ban on motorcycles has been lifted since 19 June 2008 due to escalating fuel price. This highway connect Kuala Lumpur and Selangor state. The Kilometre Zero of the highway starts at Jalan Sultan Ismail Interchange, Kuala Lumpur.
The construction of the Ampang-Kuala Lumpur Elevated Highway was approved on 16 May 1996 with Prolintas being awarded with the concession of the highway which will end in 2029. Construction began in the same year at the banks of Klang River and was completed in 2001. The highway was opened to traffic on 17 May 2001 after numerous delays, and the toll collection started on 1 June 2001. The highway was designed to accommodate future expansion of the Jelatek-MRR2 section from the current four-lane carriageway to six-lane carriageways. The expansion will take place along the northern bank of the Klang River and Ampang River.
According to the concessionaire agreement between Prolintas and the federal government, Prolintas is required to expand the highway once the average daily traffic exceeds 93,000 vehicles daily. As a result, a chicane was formed right after the EXIT 1203 Jelatek Interchange for Ampang-bound traffic. Prolintas will only be allowed to raise the toll rate once the upgrading works of the Jelatek-MRR2 section to six-lane carriageway begins.
