The container ship Dali is gone. So, too, is the bulk of the 50,000 tons of wreckage that tumbled into the Patapsco River when the Francis Scott Key Bridge collapsed on March 26. Some of the last vestiges of the Key Bridge and its demise are the two existing ramps — which led to the bridge’s main span — still standing in the water. They, too, will be gone soon as authorities make way for a rebuilt Key Bridge by October 2028.
