TBM Lowering into South Shaft on Sept 29 or 30th


The Tunnel Boring Machine (TBM) will be lowered into the South Shaft next week - on either Sept 29th or 30th, depending on conditions at the site.


The TBM will be used to bore the New Crystal Springs Bypass Tunnel under Polhemus Road. The amazing machine will eat through rock and other materials to bore the 4,200 foot long tunnel.

Watch this blog for the updated date and time the TBM will be lowered.


Neighbors - we would love to see photos you take from your homes during the TBM lowering! Please contact us via the blog and we will upload photos.
