Photographer’s Note

This is a photo of the Sarah Mildred Long Memorial Bridge, spanning the Piscataqua River, between Portsmouth, NH and Kittery, Maine. This is a vertical lift bridge built between 1917 and 1919 with great difficulty due to the strong currents and deep channel. This structure used 6000 tons of sand and 14,000 barrels of cement to pin the steel footings in place. There are three 300 foot spans crossing the river. The footings were sunk 82 feet into the bedrock to support this structure. It was designed to carry motor vehicle traffic and also railroad trains underneath.
