PORTSMOUTH, N.H. — Work is about to start on dismantling another part of the old Memorial Bridge that had connected New Hampshire to Maine.

The sounds of hydraulic hammers, cranes and excavators are expected to be heard today as crews take down the Scott Avenue approach and its supports on the Portsmouth side of the bridge. The work has been scheduled to take place over two weeks.

Workers also will need to remove a counterweight and tower on the north span, on the Kittery side. Contractor Archer Western expects the tower to be down by the end of next week.

Crews began dismantling the nearly 90-year-old bridge earlier this year. A new bridge connecting Portsmouth to Kittery is expected to open next year.
