Extended I-95 Piscataqua River Bridge Ramp Closures
Safety Concerns Require Immediate Action

MaineDOT, the Maine Turnpike Authority, and the New Hampshire Department of Transportation (NHDOT) are collaborating to make necessary improvements to the iconic Piscataqua River Bridge, and are jointly announcing the following extended ramp closures:

Closure Information:

  • Exit 7 – Northbound on-ramp for Market Street in Portsmouth from 11-12-19 to 5-14-20
  • Exit 1 – Northbound off-ramp to Kittery in Maine from 10-24-19 to 10-1-21
  • Exit 1 – Southbound on-ramp from Kittery in Maine from 6-18-19 to 10-1-21

As the construction work expands, the lane and shoulder restrictions on the bridge approaches leave less room for traffic to safely use these on- and off-ramps. Message boards, traffic control devices, and smart work zone devices will be used to notify the traveling public. Detour information is as follows for the Exit 7 Ramp Closure:

Detour Information:

  • Detour for Exit 7 northbound on-ramp closure: Take Exit 7 southbound on-ramp. Head south on I-95 to the Portsmouth Traffic Circle at Exit 5 to access I-95 northbound.
  • Truck detour for I-95 northbound on-ramp closure at Exit 7: Head east on Market Street to Submarine Way. Take a left onto the U.S. Route 1 Bypass northbound over the Sarah Mildred Long Bridge. Follow signs to the I-95 northbound on-ramp at Exit 3.

Safety is our top priority, and that is why we need to close these ramps for an extended period. Please remember to drive carefully on the detour routes and observe work zone speed limits. Construction is weather-dependent, so this schedule may change. For additional information regarding this joint project, including a map of the detour routes go to the project website at
