DelDOT says the columns can no longer support the weight of the bridge now that it rests on a newer and stronger subsurface foundation that's topped with temporary steel towers and header beams.
New columns will be erected in place of the old columns.
DelDOT is not anticipating any lane closures or shutdowns due to this work.
