PORTSMOUTH, N.H. — During the very early hours of Wednesday morning, the newest portion of the Memorial Bridge will be positioned into place as the completed north span is connected to the Kittery, Maine, side of the structure.
The float-in is expected to commence at about 1 a.m. on the Piscataqua River from the State Pier where the 300-foot span rests now and where ironworkers from Archer Western Construction have been piecing together the steel, provided by Structural Bridge in Claremont, each day.
A familiar vessel, the Cape Cod barge, will move the north span just slightly past the location of Memorial Bridge down the river following slack tide, just as all previous float-outs and the float-in of the south span occurred.
The newly completed north span is expected to also trace the same route of the south span, but will take place under the cloak of darkness rather than during the day.
The reason behind the different timing has to do with the same tidal elements, however.
In a press release last week, Stephen DelGrosso, Archer Western Western project manager, said the tide and currents are what dictate the early morning start.
