THE Captain of the Port (COTP) has established the Fort Carroll Temporary Alternate Channel, which is on the northeast side of the main channel in the vicinity of the Francis Scott Key Bridge and will provide limited access for commercially essential vessels.

The third temporary channel has a controlling depth of 20 feet, a 300-foot horizontal clearance, and a vertical clearance of 135 feet, and will facilitate additional commercially essential vessel traffic through the port of Baltimore, according to Palm Beach, Florida's Maritime Logistics Professional.

"This additional channel increases the types of vessels able to transit inbound and outbound the port of Baltimore," said US Coast Guard Captain David O'Connell, Captain of the Port and Federal On-Scene Coordinator, Key Bridge Response 2024. "We estimate facilitating approximately 15 per cent of pre-collapse commercial activity."

The Francis Scott Key Bridge collapsed into the Patapsco River in the early morning of March 26, killing six men who were working on the span at the time, after the container ship Dali lost power and crashed into a support pylon.

The Key Bridge Response 2024 Unified Command includes the US Coast Guard, US Army Corps of Engineers, Maryland Department of the Environment, Maryland Transportation Authority, Maryland State Police and Witt O'Brien's representing Synergy Marine.
