8. How many columns are in need of repair and replacement at the present time?
8. The majority of the elevated segments are scheduled to be replaced. However, there are approximately 200 columns slated to remain. For those cases the goal would be to remove the accumulated debris, power wash them and provide them with a concrete sealant coupled with a surface finish to match the color of the new bridge segments. In order to support higher truck loads, many of the columns and substructure elements scheduled to remain may also need to be strengthened. The strengthening process will take into account the structural requirements, aesthetics and low maintenance of the rehabilitated column.
