Piscataqua river bridge maine to new hampshire
The Piscataqua River Bridge is a through arch bridge that crosses the Piscataqua River, connecting Portsmouth, New Hampshire with Kittery, Maine. Carrying six lanes of Interstate 95, the bridge is the third modern span and first fixed crossing of the Piscataqua between Portsmouth and Kittery. The two other spans, the Memorial Bridge and the Sarah Mildred Long Bridge, are both lift bridges, built to accommodate ship traffic along the Piscataqua. The high arch design of the Piscataqua River Bridge eliminates the need for a movable roadway.

History
As part of the Interstate Highway System, Interstate 95 was routed along the New Hampshire Turnpike, which had opened to traffic in 1950, and paralleled U.S. Route 1 through New Hampshire's seacoast from the Massachusetts border to the Turnpike's end at the Portsmouth Traffic Circle. Between the traffic circle and the beginning of the Maine Turnpike, there was a gap in I-95 that was filled by the US-1 Bypass, crossing over the Sarah Mildred Long Bridge. Since the Long Bridge is a lift bridge with only a two lane roadway, it was far from meeting Interstate Highway standards.
The decision was made to extend I-95 north from the New Hampshire Turnpike at Portsmouth and south from the Maine Turnpike in Kittery, and join the roads with an uninterrupted high speed span over the Piscataqua. Work on the bridge was completed in 1971, and the I-95 extension to it in Maine was completed the following year.
Tragedy struck the site about midway through construction. On June 24, 1970, two of the I-beams supporting the staging area on the Kittery side of the span gave way, sending four workers 75 feet down to their death and leaving another seven injured.
