In this image construction workers from Frontier Foundations, Inc., a subcontractor for Atkinson/Dillingham Construction Co., drill the first hold for the first piling for the excavation of the Pioneer Square tunnel station at Third Avenue and Pine Street in downtown Seattle. Work on Metro Transit's $455 million, 1.3-mile-long bus tunnel began in 1987 amid concerns from local business owners that construction would affect commerce. Metro promised to reopen Pine to auto traffic during the Christmas shopping season.
