i'll always tell the taxi driver to go by PIE>BKE>Dairy Farm exit>upper bukit timah road.
any faster way?
2) Tampines to SengKang West Ave
this one i not too sure, always let the driver decide. But i only know that need to take TPE.
ps: i'm not a taxi driver. (:
1) This is by far the best route[fastest but dun kena peak period near BKE exit, always jammed like hell] . When the new express way completed next year, you may try, tamp ave 10, bartley rd, braddell rd, lornie rd, bt timah rd*, teck whye.
*must bear with some traffice lights after lornie to bt timah rd......
2) Tampines to SengKang West Ave use TPE then exit second punggol.
