3.11.2026 Elwyn Road Project Public Information Meeting

The City of Portsmouth, New Hampshire, held a public information meeting on March 11, 2026, to discuss the Elwyn Road drainage improvements project. The project involves replacing deteriorated drainage pipes along Elwyn Road, minor water main work including switching existing water services to a larger main, and reconstructing the roadway. Construction is scheduled to begin shortly and is expected to conclude by late summer or early fall 2026. The contractor will maintain water flow via temporary water mains, with short water service interruptions communicated in advance to residents. Traffic control plans include one-way alternating traffic with provisions for emergency vehicle access. The project also includes lead removal and vibration monitoring due to rock excavation. Public concerns addressed included drainage capacity and water treatment, with plans for targeted stormwater treatment at catch basins. The city emphasized ongoing communication with residents and provided contact information for project updates and inquiries.
