Mamajo East of Wells Street Bridge

Mamajo is just east of the Wells Street bridge today. Crews have completed 10,000 feet of concrete liner. The photo below shows R (ring) 2000. Each slab 5′ long = 10,000 feet complete. The tunnel is 41% complete today, slightly behind what was anticipated, but nearly halfway done. Crews will shut down for several days to install an additional slurry pump that’s needed now that they are at the 10K mark.
