The World War I Memorial Bridge is a vertical-lift bridge that carries U.S. Route 1 across the Piscataqua River between Portsmouth, New Hampshire, and Badger's Island in Kittery, Maine, United States. The current bridge was opened in 2013, replacing a bridge of similar design that existed from 1923 to 2012. A large overhead plaque carried over from the original reads "Memorial to the Sailors and Soldiers of New Hampshire who gave their lives in the World War 1917–1919."
