The reason behind the sinkholes on the 40

According to a friend of mine the sinkholes on the King Fahad Highway (40) are being caused by ongoing pipeline projects. They’re micro-tunneling under the 40 passing pipes from one side of the highway to the other and because the ground beneath the road is not stable it’s creating sinkholes [1,2].

I wouldn’t have expected micro-tunelling to have caused this; in my experience the tunelling done properly is supposed to avoid this kind of damage! I’ve only done it a few times back in the UK, but we would push the pipe through around the auger, in order to prevent causing voids. I can only think that the contractor is using too much water for the sandy soil, but [sarcasm] contractors in Kuwait are usually such high quality [/sarcasm].

Anyone else notice the high-quality substantial barricade around it? A single lump of wood, probably fallen off a passing truck!
