I always make my way in as soon as I can (from DB). My usual route is airport bus then Airport Express. I left home just after 9am and got the airport bus fairly quickly. Unfortunately, just outside Tung Chung, we came to a very flooded portion of the road, just beneath the underpass, where the road dips. We were stuck there for two and a half hours waiting for the highways truck and a man with an iron rod to clear the blocked drain! The water was thigh-deep, as evidenced by an ambulance driver who waded in to see if he could get through, lights flashing. They reversed out of the situation. We couldn't back up as right afterwards, another bus behind us did, to get to the on-ramp onto the highway, and ended up with it's rear end stuck on the road surface.
