BALTIMORE (AP) — The first cargo ship passed through a newly opened deep-water channel in Baltimore on Thursday after being stuck in the harbor since the Francis Scott Key Bridge collapsed four weeks ago, halting most maritime traffic through the city’s port.

The Balsa 94, a bulk carrier sailing under a Panama flag, passed through the new 35-foot (12-meter) channel headed for Saint John, New Brunswick, Canada. Two more commercial ships followed later Thursday, including a vehicle carrier headed to Panama.
