Singapore Buses route 99

Service 99 is a trunk route from Clementi and loop at Jurong West Street 91, passing through Boon Lay Way, Jurong East Avenue 1, Jurong West Avenue 1, Boon Lay Avenue and Jurong West Avenue 4/5.

It is a lengthy residential route, serving between the housing estates of Clementi, Jurong East, Jurong West and Pioneer Road North. Its primary role is to shuttle between different parts of Jurong, rather than connecting to all the MRT stations. A majority double-decker fleet is there to cater to the needs of all the residents.

The route connects to Jurong East MRT Station along Boon Lay Way, where it also interchanges with the two shopping malls in the vicinity: Jem and Westgate. Finally, it also runs parallel to the East West Line from Jurong East to Clementi Bus Interchange, whereby another huge loading exists between International Business Park and Jurong East, and also towards Clementi.

Route Extension to Joo Koon
As part of the opening of the Joo Koon Bus Interchange and the accompanying Jurong Industrial Service route amendments, the route 99 is extended via Jurong West Street 93 (new stops), Upper Jurong Road and Joo Koon Interchange. Since there are two new BSEP buses on service 241 of which it is added just in case the route 99 is cut, the route 99 no longer goes via Jurong West Street 92. This change took effect from 21 November 2015.

Fleet
Service 99 also consists of the Volvo B9TL Wrights of which it is upgraded from Volvo Olympian 3-axles in 2011. The Volvo B9TL Wrights are the Batch 1 version, of which it is Zenda Tan, Yo Magena Yo and Vanes Victor Tay. They are also extended to Joo Koon on 21 November 2015.
