Transportation officials say a lightning strike Monday damaged a lift bridge that connects Maine and New Hampshire, limiting the span to one-way traffic. New Hampshire Department of Transportation spokesman Bill Boynton said the Sarah Mildred Long Bridge over the Piscataqua River was in lift mode when lightning hit. He said the lift span came down at an uneven angle, causing damage that left a metal plate that is normally underground jutting out into one of the two lanes. He also said several gauges were knocked out by the lightning strike at 11:35 a.m. Monday. No one was hurt. The bridge connects Portsmouth to Kittery, Maine, and is getting heavier-than-normal use during demolition of the Memorial Bridge.
