July 11, 2013 - Pontoon T is prepared for post-tensioning work
In order to complete the final step of the repair process, crews must drill holes into the sides of the pontoon. Post-tension cables will be inserted thorough these holes and stretched tight to add strength to the concrete. Concrete "blisters" are then used to cover the ends of the cables.
