Ayer Rajah Expressway
The Ayer Rajah Expressway (AYE) extends from the western end of the Marina Coastal Expressway in the south of Singapore to Tuas in the west near the Tuas Second Link to Malaysia. Together with the Marina Coastal Expressway and East Coast Parkway, it forms a second east-west link to complement the role played by the Pan Island Expressway.
Construction on the expressway commenced in 1983, with the first two phases completed by 1988. This section involved the widening of several existing roads along the way, such as Ayer Rajah Road and Upper Ayer Rajah Road, as well as the construction of what was then the longest road viaduct, the Keppel Viaduct, from where the eastern end of the expressway commences. This section extended for Alexandra Road until Keppel Road and ended at the Teban Flyover with Jurong Town Hall Road.
In 1998, the expressway was extended to Tuas from the Teban Flyover in conjunction with the opening of the Tuas Second Link to Johor. This construction, which followed the alignment of Jalan Ahmad Ibrahim, involved the expansion of the existing road to match with the width of the rest of the AYE, construction of "filter" roads on both sides of the expressway (which eventually took the name of Jalan Ahmad Ibrahim), and the building of five flyovers and two underpasses. It meets up with the Pan Island Expressway at the Tuas Flyover.
