More delays before 'Bertha' can resume digging waterfront tunnel
"Bertha," the massive tunnel boring machine, is expected to spend the next 14 months drilling a two-mile tunnel to replace the 60-year-old Alaskan Way Viaduct.
SEATTLE (AP) - Boring at Seattle's $2 billion tunnel project has been delayed again until next week.

Officials with contractor Seattle Tunnel Partners said Friday that the boring machine is going through more tests before it can be restarted. They say some of the early material that the machine was tunneling through apparently had a chance to solidify while the machine had been shut down.

The boring came to a halt in recent weeks as longshoremen were picketing at the site due to a dispute over a handful of waterfront jobs. Gov. Jay Inslee announced Tuesday that the longshoremen had agreed to allow work to proceed as officials worked toward a larger resolution on that dispute.

Officials had hoped to restart boring work Friday. They are now looking at some point early next week.
