UPDATE: Bertha’s Repair Further Delayed

Repairing the tunnel-boring Bertha hit more delays this past week when it was announced the deep access pit that is being built to reach the front side of Bertha would be delayed by a month. Crews need more time to grind and chisel through concrete so the 120-foot deep vault in front of Bertha will be completed in August instead of July as originally planned. Chris Dixon, project director for Seattle Tunnel Partners, believes Bertha will still be fully repaired by March because the repairs had a two-month cushion added to the schedule. While Seattle Tunnel Partners is confident that the machine will be ready to complete the remaining 8,200 feet of tunneling needed for the Alaska Way Viaduct Replacement Tunnel project on time, Washington Department of Transportation is not as optimistic.
