Another milestone has been reached in the Bolton Feedermain Project’s micro-tunnelling phase. After weeks of work and preparation as well as dealing with a few Mother Nature related delays, Project Manager John Glass reports that crews are ready to begin the first tunnelling operation. The micro-tunnel machine itself will be lowered into Shaft 4 and it’s planned this week to begin the first drive. Dependent on earth conditions the drive is estimated to take about 5 – 8 days.
