A lot of salt has been moving up the North River this month, headed for the Port of Coeymans to restore municipal supplies depleted during the harsh winter. Some has come on bulk ships heading upriver, and some has come by barge, lightered off a series of bulk ships that have arrived from Egypt and anchored in the Upper Bay. On Wednesday, CMT’s Mackenzie Rose came by with a cargo loaded in the bay, the second in less than a week. Thursday evening, Thomas Dann came through with a similar cargo just before sunset.
