Prescott Park is a ten-plus acre waterfront park in Portsmouth, New Hampshire, United States. The land was purchased in the 1930s by two sisters, Josie and Sarah Prescott. The sisters, public school teachers, had used an inheritance to systematically purchase and clear properties along the Piscataqua River. The sisters' goal was to create a public waterfront park, free and accessible to all, replacing what had become a run-down and seedy industrial area. In 1949 the Prescott sisters' trust was established with $500,000. The park was willed to the city of Portsmouth in 1954 for public enjoyment.Prescott Park comprises over 10 acres (4.0 ha) of waterfront property along the Piscataqua River. Since 1974 it has hosted full outdoor productions of Broadway plays for family audiences during the summer months. There are also many flower gardens and water fountains maintained since the mid-1960s. The park is directly across Marcy Street from the Strawbery Banke Museum. The Players' Ring Theater is located in the park.

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." 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. New Hampshire and Maine designated the bridge as part of their State Bicycle Routes, and the bridge is part of the proposed East Coast Greenway.
