To get from Sihanoukville to where we were staying we had to take a main road that was constantly used by trucks getting to and from construction sites. It was a dirt road that had been torn to pieces, including major major potholes, diversions into oncoming traffic to avoid these, huge traffic jams due to this, and at one point the powerlines had collapsed across the road, and had been left there, running live with cars literally driving over them all day long. Definitely a huge accident waiting to happen.
The local infrastructure is just not able to sustain this level of development. And the unfortunate thing was, the development companies were not giving back enough to actually fix up the roads and other chaos they caused, so the locals end up worse off.
