ada alternative route /bypass before the flyover.

jalan tu dah tutup lama dah..if am not mistaken shud be open back this march/ may (not sure forget edit) but now no chance lerr

somethg like this..lazy to edit much

RED = closed (for many months edi)
Green = to putrajaya
Yellow = to toll (KLIA/ Shah Alam)

2-3 years i think but have been closed for past 3 months..not so sure la mana mau igt.

anyway the road at science park actually not officially open..even got signboard use at ur own risk something like that but am not sure abt the flyover ....flyover is to puchong housing area (nusa putra)
science park in the map above (cant be seen in the map tho) is below the yellow arrow.
