No train delays when [midline ellipsis] C and NW replaces old truss spans
Method used by Chicago and North Western for replacing eight wrought iron through truss spans with 16 shorter deck plate girder spans without use of falsework or temporary bridge and without interference with train operation; bridges, separated by island about 540 ft long, cross two channels of Menominee river at Marinette, Wis.
