Replacement on this unusual bridge is ongoing as of September 2021. I am not sure how much will be replaced..new approaches have been installed on the south end, and the north end has new piles driven for approaches. A single pile has been driven under the north span.
The three girders at this bridge are all slightly different with modifications. I suspect that these girders were all moved here.
