Memorial lifting bridge

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. A large overhead plaque facing traffic on the bridge reads "Memorial to the Sailors and Soldiers of New Hampshire who gave their lives in the World War 1917-1919."

The lift span can be fully opened to allow large commercial vessels to pass. During summer, the lift section remains partially elevated every half-hour between 7 a.m. and 7 p.m. for about 15 minutes. This allows smaller commercial and recreational boat traffic. The bridge is currently the only one of the three Piscataqua River bridges with provisions for pedestrians and bicycles. This bridge replaced the original structure that was completed in 1923 and closed in 2011.

The opening of the new bridge in August 2013 was reported in the local paper thus:-

New Hampshire and Maine celebrated the opening of a new bridge Thursday that has become a steel symbol of their past cooperation and their commitment to future commerce.
The $81.4 million Memorial Bridge between Portsmouth and Kittery, Maine, replaces one that was built in 1923 and closed in 2011. As she did 90 years ago at age 5, former Portsmouth mayor Eileen Foley did the ribbon-cutting honors, riding across the bridge in a golf cart with a bouquet of flowers on her lap. The crowd cheered as she cut the ribbon, then sang "God Bless America."
