All underground utility work has been completed ahead of schedule. Road reconstruction activities between Taft and Edgewood Roads, including base course paving, are scheduled to begin the week of June 8 and continue through the week of June 22, 7 am to 6 pm. During this phase of work, westbound traffic on Elwyn Road will be detoured via Taft Road to Wilson Road, and then to Route 1 (Lafayette Road). Eastbound traffic from Route 1 (Lafayette Road) will be maintained with one lane of travel. Local traffic will be accommodated. Two-way traffic will be restored at the end of each workday. Signage, flaggers, and police details will be stationed at strategic locations along the detour route to direct and manage traffic through the Elwyn Park neighborhood. Final paving and restoration -- including loam and seeding of disturbed areas -- will take place in the fall. The Department of Public Works hosted an Elwyn Road Reconstruction Project Public Information Meeting in the DPW Training Room (680 Peverly Hill Road in Portsmouth) on Wednesday, March 11, 2026.
