SEATTLE -- Bertha made it!



Bertha, the machine digging a 1.75 mile tunnel under Seattle to replace a waterfront bridge with an underground roadway, completed her journey on Tuesday.



It's no secret that the project has had its fair share of troubles. The $3.1 billion tunnel project is scheduled to open in 2019, four years behind schedule. The original completion date was the fall of 2015.



Twitter users didn't forget.

Crews will break down the boring machine as others prepare the inside of the tunnel to handle double-decker lanes of highway that will replace the Alaskan Way Viaduct, which was damaged in a 2001 earthquake.
