|New Revised Schedule For Memorial Bridge Lift Span "Float Out"
The likely time frame during which the Memorial Bridge lift span will be floated out has been expanded to as late as the night of Wednesday, February 8, 2012.
The barge "Cape Cod" will be put into place during daylight hours on Tuesday, February 7, between 10:00 am and 3:00 pm. The actual float-out will likely occur sometime within 16 hours following this time period. This is within the 72-hour time period approved by the U.S. Coast Guard – from 7:00 am on February 6 to 7:00 am on February 9.
The New Hampshire Department of Transportation (NHDOT) will again issue an advisory as soon as feasible prior to the float-out.
Work is continuing in preparation of this first major event associated with the demolition of the Memorial Bridge that crosses the Piscataqua River between Portsmouth, New Hampshire and Kittery, Maine. This event requires the use of two 250-ton cranes on barges, four tugboats, and the Cape Cod barge that carries four towers equipped with 300-ton hydraulic jacks. The process begins with positioning the crane barges adjacent to the navigation channel and the Cape Cod under the lift span.
The Cape Cod will be moved into position first. The wire ropes connecting the lift span to the counterweights will then be cut, freeing the two-million pound lift span. The barge will then be moved by the tugs out of the main navigational channel and over to an area near Prescott Park or the Port Authority Pier, depending on the time of removal, to be secured for shipment.
The public is welcome to observe the lift span removal and float-out operations from safe nearby locations. While the work zone itself is not open to the public, good views can be obtained from Prescott Park, Four Tree Island, and Peirce Island.
