Portsmouth bridge repairs to take six to eight weeks
PORTSMOUTH — Repair work will soon begin on the Sarah Mildred Long Bridge, requiring daytime lane closures with alternating one-way traffic for six to eight weeks.
During this time, New Hampshire Department of Transportation bridge maintenance crews will install supports under certain steel floor beams of the bridge spans. According to the DOT, the work is needed to retain the current 20-ton load restriction on the bridge.
The bridge, constructed in 1940, is scheduled for replacement by 2017. It connects Portsmouth with Kittery, Maine, via the US Route 1 Bypass and provides rail access for the Portsmouth Naval Shipyard.
The Maine Department of Transportation is the lead agency on the bridge replacement project.
