Working on the dam

Maddie K., a 47-year old, 2,000 HP tug operated by New York State Marine Highway Transportation, was on the North River Thursday, maneuvering barges at the Gateway Tunnel project’s large coffer dam off Pier 66. Work is underway here to reinforce the riverbed in preparation for digging the new rail tunnel below. The dam currently divides the river into two channels but is expected to move towards the Manhattan shoreline later this year.
