3 months since visiting here on the Western Slopes....south portal. The chalk landscaping progresses and is taking shape though there is still significant amounts of material to shift. Also last chance to see before the set up changes as factory decommisioning begins.
scanning right to left:
- the viaduct factory will be decommissioned later this year.
- the tunnel segment factory stopped producing cement rings last month and is being decommissioned. 2 tunnel boring machines are due to finish their 10 mile journey next month as they approach north portal at South Heath in Buckinghamshire.
Work continues excavating 38 cross passages in the tunnels
- the slurry treatment plant is due to close shortly as tunnelling comes to an end and the final slurry from the tunneling is delivered.
