Piscataqua River Bridge Rehabilitation Project - What to Expect (Updated 02/13/20)

Maine Ahead Project Kittery

February 24, 2020 Update:

Beginning on Monday, February 24th, the "Maine Ahead" project will begin a new phase of safety improvement work on the Piscataqua River Bridge. Crews will be replacing bridge joints that date back to the original construction of the bridge a half-century ago.

This phase of joint replacement work will require the right travel lane to be closed on the southbound side of the bridge. This closure will restrict the southbound side of the bridge to two lanes. It will not be reopened to three lanes until this phase of the joint replacement work is complete.

In a few weeks, the joint replacement work then begin on the northbound side of the bridge. This work will require a similar right travel lane closure on the northbound side.  These lanes must be closed in order to work on the bridge joints. These traffic restrictions are also necessary for the safety of the project crews and the traveling public.

The project team hopes to be able to reopen these travel lanes as soon as this phase of the bridge joint replacements is complete, but the traffic restrictions could last through mid-May. The project team is committed to keeping three lanes of travel open on both sides of the bridge during peak travel periods (between mid-May and the day after Labor Day).


February 13, 2020 Update:

All three lanes on the Piscataqua River Bridge will remain open in both directions throughout the holiday weekend (Saturday 2/15 - Monday 2/17).  

The Southbound right lane will be closed from 5:30 AM on Tuesday, February 18, through 3:00 PM on Friday, February 21.  The right Northbound lane will also be closed from the New Hampshire side of the bridge, through Mile Marker 2 from 5:30 AM on Tuesday, February 18 to 12:00 PM on Friday, February 21.


January 8, 2020 Update:

As we move through the winter months, please remember that lanes are narrow during construction.  In inclement weather situations, please allow plenty of room and use caution while driving so plow drivers can complete their snow operations in order to keep both the public and work crews safe.

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.

To keep up to date on the bridge project:

  • Visit the "Maine Ahead" website here, to sign up for traffic alerts from MyTrips New England 511.
  • Visit "Maine Ahead News" on Facebook and Twitter.
  • Keep an eye out for electronic message boards.
