Alice doing well
The tunnel boring machine known as Alice is making good progress on constructing the second motorway tunnel for the NZ Transport Agency’s Waterview Connection project. Alice has excavated just over a quarter of the 2.4km-long southbound tunnel. It is 22 metres below ground and has passed under Great North Rd. ‘‘Everything is on track for [Alice’s] planned breakthrough at Owairaka in mid-spring,’’ Transport Agency’s Highways manager Brett Gliddon says.
