Piscataqua River Bridge Rehabilitation Project - What to Expect (Updated 11/5/19)

Maine Ahead Project Kittery

November 5, 2019 Update:

As the Piscataqua Rive Bridge Rehabilitation Project expands, lane and shoulder restrictions on the bridge approaches leave less room for traffic to safely use these on and off ramps.  While the following closures create inconveniences, the changes are necessary to ensure the safety of both the traveling public and project crews.

Closure Information:

  • Right Lane on I-95 Southbound (Mile 1), at 6:00 AM on 11/12/19, with the lane re-opening by 4:00 PM on 11/16/19.
  • Right lane on 1-95 Northbound (Mile 0), at 6:00 AM on 11/13/19 with the lane re-opening by 6:00 PM on 11/14/19.
  • Exit 7 - Northbound - Market Street in Portsmouth from 11/12/19 to 5/14/20
  • Exit 1 - Northbound - Kittery in Maine from 10/24/19 to 10/01/21

September 4, 2019 Update:

This week, crews will be closing one lane on I-95 from Mile 2 southbound across the Piscataqua River Bridge. The lane closure will remain in effect during the week from 8:00 PM on Tuesday 9/3 through 6:00 AM on Saturday 9/7. All lanes will remain open during the weekend.


Work has recently begun on the Piscataqua River Bridge connecting Kittery, ME and Portsmouth, NH.  The I-95 bridge project work includes:

  • Resurfacing the bridge
  • Repairing concrete on the deck beneath the bridge surface
  • Replacing joints, drains, exterior bridge rails, concrete overhang of the deck, and the median barrier.
  • Patching concrete on bridge piers
  • Upgrading the electrical system with 41 new street lights and new webcams
  • Highway work north of the bridge on the Maine Turnpike, including mill and fill, reconstructing shoulders and replacing median barriers.

Additionally, the bridge is being primed for a possible intelligent transportation system that will allow the breakdown lanes to be used for travel when there are high traffic volumes.

Because this bridge is the most heavily traveled bridge in Maine, most of the project work is being completed during the overnight hours.  This schedule means that some residents living close to the bridge may hear construction sounds overnight.  While the noise is unwelcome, MaineDOT and the project team have stated that it is unavoidable and will continue intermittently throughout the project.
