MASSENA, N.Y. (AP) — Authorities say a freighter carrying soybeans is immobilized by ice in a lock on the St. Lawrence Seaway.

The Saint Lawrence Seaway Development Corp. says tugs have been working to dislodge the bulk carrier Federal Biscay from the U.S. Snell lock at Massena.

Once the Marshall Island-flagged vessel is freed, four other vessels can get through the lock and depart the Seaway.

Officials say the U.S. portion of the Seaway will close to commercial traffic for the season after all the vessels have departed.
