SEATTLE -

State officials say they plan to hold the contracting team accountable for repairs or any potential cost overruns on a massive tunneling project in Seattle.

Gov. Jay Inslee said yesterday the state will insist that contractors honor their contract.

Seattle Tunnel Partners is working with the machine's manufacturer to determine how to fix the broken seals surrounding the main bearing of the machine, which is 60 feet under downtown Seattle.

The group's director Chris Dixon says he is sure the problem can be fixed.

But transportation officials announced late Monday that it could take months to fully repair the machine.

The total viaduct replacement is estimated to be a $3.1 billion project. The tunnel project is supposed to be finished in late 2015.
