Keperluan cermin kembung di Jalan Kolam Air

Earlier, I had received news about a vehicle crashing into the slope of Bukit Mas while coming down via sharp turn at Jalan 1/4B. I see there is a need of at least a convex mirror and speed breaker.

We had written to DBKL urban transportation department about this critical issue. I am looking towards their action at soonest possible.
