Description
On of the older bridges of Portsmouth,New Hampshire, taken on a rain foggy day.
The Sarah Mildred Long Bridge is a lift bridge that carries the US 1 Bypass over the Piscataqua River between Portsmouth, New Hampshire and Kittery, Maine. The bridge is a double deck truss bridge, with the US 1 Bypass road deck above and a railroad bed below.
The bridge features two separate movable spans. While the main lift span and its towers are the obvious primary moving feature, the second moving span is only apparent to water and rail traffic. On the north side of the bridge, the first non-trussed section of rail bed lifts up and moves south as a retractable bridge, coming to rest on top of the rail tracks inside the truss. This creates a waterway large enough for most recreational boats to pass through without the need for interruption of automobile traffic on the bridge.
Completed in 1940, the bridge is the second to carry motor vehicle traffic between Maine and New Hampshire at Portsmouth, and replaced a river crossing dating from 1822. The bridge was the direct result of the work of the Maine-New Hampshire Interstate Bridge Authority, which had been formed in 1937. The major goal of the bridge project was to relieve congestion in downtown Portsmouth and Kittery, where US 1 crossed the river via the Memorial Bridge, which had opened in 1923.
