Ayer Rajah Expressway

The Ayer Rajah Expressway (abbreviated as the AYE) extends from the western end of the East Coast Parkway in the south of Singapore to Tuas in the west near the Tuas Second Link to Malaysia. Together with the East Coast Parkway, it forms a second east-west link to cmpliment the role of 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 constuction of what was then the longest road viaduct, the Keppel Viaduct, from where the eastern end of the expressway commences. It extended for 13 kilometres and ends at the Teban Flyover with Jurong Town Hall Road.

In 1998, the expressway was extended to Tuas from the Teban Flyover to tie in with the opening of the Tuas Second Link to Johor. This construction, which followed the alighnment 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 are 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.
