Alaskan Way Viaduct
The latest inspection of the Alaskan Way Viaduct found additional ground settlement, wider cracks and two new cracks on columns near the area where the Seattle Tunnel Partners are working to fix Bertha, the giant tunnel boring machine that is supposed to dig the highway tunnel to replace the viaduct along Seattle’s waterfront.
A state lawmaker says he wants to block more state money from going to keep transit buses moving through the construction zone for the Alaskan Way Viaduct tunnel replacement.
Workers at the Seattle tunnel project have started pulling pieces of the broken tunnel machine called Bertha to the surface for repairs.
The contractors building a tunnel under Seattle have invited the media to a special viewing of Bertha, the world’s largest tunnel boring machine, as they prepare to pull it out of a pit for repairs.
Bertha, Seattle’s tunnel machine, achieved what officials called “a significant milestone” on Thursday when it broke through a 20-foot-thick concrete access pit wall into a shaft so that it can be pulled out and repaired.
Bertha has reached her goal
Bertha is on the move.
The Alaskan Way Viaduct has settled up to a quarter inch during the past month, but transportation officials say the waterfront structure is still safe.
The manager for the troubled Alaskan Way Viaduct replacement project told lawmakers Thursday that the state and the contractor are still battling over tens of millions of dollars in repairs dating back to 2012, but even if the contractor declares bankruptcy tomorrow, the project could still be completed.
A new highway tunnel through downtown Seattle won’t be open until August 2017, about 20 months behind schedule, state transportation officials said Monday.
