Site work and paving for a road / highway in Portsmouth, New Hampshire. Conceptual plans call for site work for a road / highway; and for paving for a road / highway.

A now abandoned rail corridor between Portsmouth and the Massachusetts border includes 3.6 miles in Portsmouth. This corridor has been designated as the future off-road route of the NH Seacoast Greenway. In 2019, the NH Department of Transportation acquired the rail corridor and also has secured some federal funding to convert it to a multiuse trail. Design and construction of the trail will be done through a collaboration between NHDOT and corridor communities. The project cost estimates assume that NHDOT will be responsible for initial design, permitting and engineering as well as construction costs to create a gravel trail base. The City's portion of the costs will include additional costs required to build a paved surface as well as any amenities such as trail access areas and interpretive signs. This should be reassessed in FY24 based trail progress. As of December 11, 2024, this project is included in the Portsmouth School Department Fiscal Year 2025-2030 CIP. Further information regarding a design firm and timeline for construction has not yet been established. Funding is allotted for FY 2026, 2027, and 2029. *Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change. The content management team will continue to pursue additional details as they become available.
