Removing column forms

The 130 ton arch is supported by two concrete columns. During the week of July 5th, the steel forms were removed, revealing the cement inside.

The pieces of steel forms are stacked on site and then sent off to be used on another job.

Supporting structure

The forms for the columns are made of curved steel sections bolted together. Here, the far sides of the columns are in place but the near sides are still open while the steel workers install the rebars. Later, the columns will be completed by bolting on the remaining steel forms, and then filled with cement. When cured, the forms will be removed, revealling the finished concrete column.

Scaffolding has been erected around both columns, and temporary steel beams cross the street. A working platform is being built on top of the steel beams.
