...Something unknown, engineers say — and all the more intriguing to many residents for being unknown — has blocked the progress of the biggest-diameter tunnel-boring machine in use on the planet, a high-tech, largely automated wonder called Bertha. At five stories high with a crew of 20, the cigar-shaped behemoth was grinding away underground on a two-mile-long, $3.1 billion highway tunnel under the city’s waterfront on Dec. 6 when it encountered something in its path that managers still simply refer to as “the object.”..

 

Guesses for the identity of "The Object" already offered:

 

A Kimberlite deposit

Tommyknockers

Monolith [A La 2001]

Megatron

Godzilla

 

Some suggestions less credible than others...

Just a few days before the SR 99 tunneling machine started tunneling under the Alaskan Way Viaduct, the Washington State Department of Transportation flew a video-equipped drone through the SR 99 tunnel to show Seattle Tunnel Partners’ construction progress. On an average day, the tunnel is bustling with construction. To avoid disrupting crews, this video was recorded in between regular work shifts.

I was disappointed to discover the mystery blockage was a pipe (although better than a pipe having a mystery blockage i suppose)
