When I was in Yangshuo a few weeks ago, I could see they were building a new expressway from Yangshuo to I think Guangzhou or it could have been Shenzhen? I was told but I forgot which of the two cities it will link to. It seems this will really help travelers that want to go straight from Hong Kong to Yangshuo but can't deal with the overnight bus. It would eliminate the need to fly into Guilin. You could arrive at Hong Kong Airport at noon and still make dinner in Yangshuo.
Does anyone know the particulars of this expressway? Does it go to Guangzhou or Shenzhen? When is it scheduled for completion? Will it really let you get from Hong Kong Airport to Yangshuo in around 6 hours?
