PORTSMOUTH, N.H. — A group that has been studying replacement or repair options for two bridges between Maine and New Hampshire are looking at a so-called hybrid structure that wouldn’t need to be raised as often.

Members of the Maine-N.H. Connections Study group say one option for replacing the Sarah Mildred Long Bridge between Kittery and Portsmouth would be a double-lift bridge based on one in Portland, Ore. That bridge has a lower deck for railroad and pedestrian traffic and an upper deck for cars.

Foster’s Daily Democrat reports that the study group is considering a bridge with a higher structure so that the lift portion would only have to be engaged when the tallest of ships pass down the Piscataqua River.
