A third temporary channel for boats to enter and depart the Port of Baltimore has opened, expanding further shipping access as collapsed sections of the Francis Scott Key Bridge are salvaged before the span can ultimately be rebuilt. The alternate channel, located to the northeast of the fallen bridge, is open to `commercially essential vessels,` port officials announced late Friday.

The new temporary path, with a controlling depth of 20 feet (6.1 meters), a horizontal clearance of 300 feet (91.4 meters) and a vertical clearance of 135 feet (41.2 meters), allows a greater variety of vessels to access the port while crews work to reopen the main channel, Coast Guard and port Capt. David O`Connell said in a news release.
