PORTSMOUTH, N.H. — The steel that will be used to rebuild a bridge connecting New Hampshire and Maine is expected to arrive in October.

The main contractor for the Memorial Bridge says the structural steel is being fabricated in Claremont.

A new concrete bridge deck also is planned for this fall.

Crews have run into debris in some of their drilling work on one of the piers. Contractor Archer Western says the wood, steel and old piping has slowed down some of their work. As a result, they have been working double shifts to catch up.

The new bridge between Portsmouth and Kittery, Maine, is expected to be completed by July 2013. The old Memorial Bridge connected the two communities for nearly 90 years.
