It seems like more than a few things are complicated when it comes to Bertha. Last week, tunnel contractors told the state Department of Transportation when the 57-foot tunnel boring machine would get back to work, but the DOT doesn't want to share the details until it has fully reviewed the plan, KOMO reports. According to a DOT spokesperson the 250-page report shows "a complicated schedule," different from prior schedules released by the project's contractor.
In the spring, the tunnel's contractors projected a November 2017 completion date. Until we hear more, we're taking that with a grain of salt.
