City Construction Season Resumes April 7, 2025

The City of Portsmouth NH Department of Public Works (DPW) announces that several seasonal construction projects throughout the City are scheduled to resume on April 7, 2025, with additional work to follow. 

Projects include:

• Islington Street Project – Construction resumes on Monday, April 7, 2025. An on-site, in-person Q&A session is planned in front of The Kitchen and Caffe Kilim (163-171 Islington Street) on Friday April 4, 2025, at 3 pm. Most of the utility work has been completed. However, underground infrastructure work is still needed at the Congress Street, Middle Street, Islington Street intersection, and several other areas. The balance of this year’s work will involve finishing the tree-planting, installing sidewalks, lighting, road paving and striping. It is estimated that all work should be completed before summer’s end. For more information, visit: the project page.  
• Maplewood Avenue Bridge Project – The bridge is scheduled to be closed from April 7 through mid-June 2025 for the installation of water mains.
