The federal agencies announced on Monday that they had restored full access to commercial maritime transit in the Port of Baltimore following the removal of more than 50,000 tons of debris resulting from the collapse of the Key Bridge on March 26.

In March, the cargo ship Dali collided with the Francis Scott Key Bridge at Baltimore. Six people were killed and a major transportation route for the U.S. Northeast was paralyzed. U.S. Army Corps of Engineers announced on Monday that a survey certified the riverbed safe for transit. The Fort McHenry Federal Channel has been restored to its operational dimensions of 700 ft wide and 50 ft deep.

The channel will be able to accommodate two-way traffic, and all safety measures that were necessary due to the temporary narrowing of the channel will no longer be required.

More than two months passed before the last piece of wreckage was removed by the U.S. Army Corps and U.S. Navy supervisor of Salvage and Diving. The Dali was moved safely on May 20.

Over 1,500 responders, along with 500 experts from all over the world, operated a fleet boats in the operation, which involved 56 federal agencies, states, and localities.

The surveying and removals of steel below and above the 50-foot-mud-line continue in order to avoid any impact on future dredging and to continue transporting wreckage to Sparrows Point to continue further processing.

The FBI launched a criminal investigation into the collapse in April. The National Transportation Safety Board reported last month that the Dali had lost electrical power multiple times before it crashed onto the bridge, including a blackout while in port maintenance and just before the crash.

Maryland expects to complete the project by 2028. (Reporting and editing by Leslie Adler, Lincoln Feast and David Shepardson.)
