City Announces Start of Kearsarge Way & Market Street Bridge Repair Projects

April 24, 2020

The Department of Public Works has announced that two bridge repair projects are tentatively scheduled to commence Monday, April 27, 2020.  The two projects are:

  •  Kearsarge Way Bridge over Pan Am Railways into the Atlantic Heights Neighborhood
  • Market Street Bridge over the North Mill Pond Tidal Basin.

Work on the Kearsarge Way Bridge includes: repairs to the concrete bridge deck, installation of a new barrier membrane, replacement of the expansion joint, substructure concrete repairs and hot bituminous paving. Repairs to the Market Street Bridge include replacement of the expansion joint system and the bridge approach rail. Both projects are part of the City’s Bridge Capital Improvement Program.

Starting on or after April 29, the Market Street Bridge will be reduced to one eastbound and one westbound lane of traffic between the Sarah Mildred Long Bridge and the traffic signal at Noble’s Island, 24/7, for the duration of the project. Kearsarge Way Bridge construction will start after construction signage is in place, on or after May 4. The Kearsarge Way Bridge will be reduced to a single lane of alternating traffic, controlled by temporary traffic signals on each side of the bridge, 24/7, for the duration of the project. Construction will take place Monday through Friday, 7 am to 6 pm. Pedestrian traffic will be maintained at all times during both projects. Construction on both projects is anticipated to be completed in the fall.

For public information purposes, a presentation on the Market Street and Kearsarge Way Bridges Projects is posted to the City website on the page dedicated to the projects.  The public is invited to submit questions on the presentation and/or project by emailing raflynn@cityofportsmouth by Tuesday, April 28. Written questions and answers will be posted alongside the presentation within 48 hours thereafter.  For more information on this project you can contact Ryan Flynn, Construction Project Coordinator, at 603-766-1413 or
