PORTSMOUTH, N.H. — Some repair work is getting under way at the Sarah Mildred Long Bridge connecting New Hampshire to Maine.
Crews are installing supports under steel floor beams on piers of the New Hampshire approach spans. Transportation officials say the work is needed to retain the current 20-ton load restriction on the bridge.
All work is being done during daytime hours and is expected to take six to eight weeks to complete.
Daytime lane closures with alternating one-way traffic on the bridge will be necessary periodically in order to complete the work.
The bridge carries the U.S. Route 1 Bypass over the Piscataqua River between Portsmouth and Kittery, Maine.
The replacement of the bridge is currently scheduled to begin in 2015. It is the No. 1 red-listed bridge in New Hampshire.
