PORTSMOUTH, N.H. — The new Memorial Bridge connecting New Hampshire to Maine is still scheduled to open to traffic this summer.

Contractor Archer Western has put into place the new south span and a concrete deck. It has started erecting the south tower.

Steel tower pieces made by Structural Bridge in Claremont are being erected piece by piece by a barge-mounted crane near the south span. That will take about month to complete.

Plans are for the north span to be completed in March and floated into place at low tide, using the same process as used for the south span.

While the bridge between Portsmouth and Kittery, Maine, would be open this summer, Archer Western says final work, including landscaping and cleanup, will take until the end of the year.
