Transforming Bertha’s disassembly pit
Crews working for Seattle Tunnel Partners tie rebar for a wall just north of the bored section of the SR 99 tunnel. The work is happening inside the pit near Seattle Center where the SR 99 tunneling machine Bertha was disassembled after completing tunnel mining in April 2017. Crews are now converting the pit into a section of the tunnel.
