From the video, look like it the pasir panjang viaduct towards west coast. She was lucky there no towhead with 40ft 30 tons trailer behind the group. I always wonder are cyclists allow to go up the viaduct? This vehicle viaduct is especially dangerous as it was specifically built to let towhead to transfer containers between brani and pasir panjang containers terminals. Towheads hundreds if not thousand of trips per day 24/7. Each container give driver about $5 per trip on top of basic salary. So many will thunder along the viaduct as fast as they dare. There many potholes as the viaduct maintenance crews cannot keep up with the wear and tear.
