STILLWATER, Minn. (AP) — A walkout by union ironworkers is slowing construction work on the St. Croix River bridge connecting Minnesota and Wisconsin.
Michael Beer, a Minnesota Department of Transportation project manager, says as many as 120 ironworkers left the site Friday.
Beer tells the Star Tribune the ironworkers have been replaced by about a dozen supervisors.
The walkout involves a contract dispute between the ironworkers’ employer, J and L Steel of Hudson, and the project’s general contractor, Lunda-Ames Joint Venture.
Beer said the ironworkers have been tying rebar before concrete is poured. Work continued on the site until Tuesday as carpenters and concrete pourers worked on completed metal portions.
The ironworkers belong to Iron Workers Local 512 in St. Paul. A union official did not immediately return a phone message Tuesday.
