The north span of the new Memorial Bridge connecting New Hampshire and Maine is getting ready for its big entrance. The span is expected to be floated in at about 1 a.m. Wednesday. Stephen DelGrosso of contractor Archer Western tells the Portsmouth Herald, the tide and currents dictate that the float-in start early. The move toward the Kittery side of the bridge would be completed by 8 a.m. The barge Cape Cod – on which the north span is being built at the Port of New Hampshire -is expected to be moved through the Sarah Mildred Long Bridge on Tuesday afternoon, then be tied up on the downriver side awaiting the float-in. The new Memorial Bridge connecting Portsmouth and Kittery is scheduled to open to traffic this summer.
