PORTSMOUTH, N.H. — Now that the center span of the Memorial Bridge connecting New Hampshire and Maine is gone there’s more demolition work scheduled for next week.

Keith Cota of New Hampshire’s Department of Transportation says a 750-ton crane barge will arrive to dismantle the two towers once used to raise and lower the center span. Pullies at the top of the towers will have to be removed first, followed by 250-ton counterweights, then truss sections of the towers.

Cota tells the Portsmouth Herald after the towers are removed, the fixed spans will be the next to go.

A new bridge is expected to open next year.
