SEATTLE (AP) - Digging resumed Thursday in a pit near the Seattle waterfront that will be used to repair a huge machine that broke down while trying to bore a highway tunnel under the city.

The Seattle Daily Journal of Commerce reports (https://bit.ly/149Uxwh) the pit is about 90 feet deep and needs to be about 30 feet deeper to reach the boring machine called Bertha.

Bertha broke down more than a year ago. Digging the repair pit has also has had its problems. Work was stopped in December because of settling in the area suspected of cracking walls.

The contractor, Seattle Tunnel Partners, and state Transportation Department are hoping the new 2-mile Highway 99 tunnel will be completed in late 2017 so the aging Alaskan Way Viaduct can be demolished.
