The official name is the Sarah Mildred Long Bridge. The original bridge was built in 1940 between Portsmouth, New Hampshire, and Kittery, Maine. It was built as part of a bypass to relieve the traffic on US-1 and the 1923 Memorial Bridge. The bridge also supported a Boston & Maine branch to South Berwick, ME. The Guilford Rail System/Pan Am/B&M branch has been cut back and now supports only the Portsmouth Naval Shipyard (95 photos). It also carried the traffic of I-95 across the river between 1960 and 1972 when the Piscataqua River Bridge and turnpike extensions were finally opened to carry road traffic high above the river with three lanes in each direction. The I-95 bridge is the steel arch bridge you see in the background of the following street view.
A replacement bridge was scheduled to be opened in Sept. 2017, but the old bridge was scheduled to be closed in Nov. 1, 2016. The old bridge must have been in really bad shape to plan forcing road traffic to use the interstate after the last the last train crossed it on Dec. 9, 2015. It was "carrying two loaded spent nuclear fuel flasks from Kittery Ship Yard en route to Idaho." [Bridge Hunter] But the lift span broke in August, 2016. Rather than spend the estimated $1 million to repair it, they just closed it a couple of months earlier than originally planed. Design of the new bridge started in 2013 and construction started in January, 2015. [MDOT]

Key Bridge Attributes
The use of one lift span that can carry both road and rail traffic and that can be positioned at three levels --- open, road traffic, and railroad traffic --- also justifies the "bridgeRare" label.
This is the Facebook posting that provided the name so that I could learn about this bridge.
