Ironworkers known as “Rod Busters” are seen here assembling a steel rebar caisson for the Ohio River Bridges Project in Louisville Kentucky. There is also a completed caisson in the background on the work barge. These caissons will be inserted into the steel cylinders that are in the right hand side of the image when those cylinders are placed in the river to build the piers for the new bridge. It was early in the morning and a fog bank was coming in from the east which diffused the light and lent an ethereal quality to the morning sunlight.
