Any reliable links that investigate the construction costs that include the true number of deaths and injuries?  We came here 16 years ago and live a few miles south of Hua Hin.  The road trip coming to Bangkok and leaving Bangkok has become more and more dangerous.  As cited above the roadway is in terrible shape and the risk of falling debris is worsening.

I looked at those flimsy Y shaped concrete supports - and wonder how easily they would fall down, let alone the road on top. And how good are the foundations. Here in Udon Thani they built a new flyover on the ring road, supports are much more massive. It was built to last.
