A multi-month strike by 330 workers represented by Teamsters union Local 174 working for six companies in Washington state's Puget Sound region has slowed four major Sound Transit rail construction projects and disrupted others.

On Jan. 10, the strike extended to the Port of Everett's 55,000-ton bulk storage cement facility for a three-hour stretch. Striking concrete mixer drivers and plant workers employed by Lehigh Northwest Cement Company shut down all operations at the port, the second-largest export customs district in Washington state.
