Quake roads "all now reopened"
Each night before they go to bed, the workers park large machinery just out of their temporary shelter to block the falling rocks.
"Local people call the mountain Guizhaoshou (devil's greeting)," Li said.
"Many times when we woke up, we found machinery that had been broken by fallen rocks."
There is a risk even when it is deep in winter - not a rainy season, he said, as winds set off rock falls.
But work still goes on, Li added. Following his fingers, workers were busy at the foot of the "devil's greeting".
In order to finish the bridge, the whole team works for 24 hours a day and on two shifts.
"Now we hope a new bridge will be here after the Chinese New Year, allowing vehicles passing by to get further away from the devil's greetings," Li said.
