Section of Henry Law Avenue closed for construction

posted on 8/11/2026

A section of Henry Law Avenue is closed as part of the first phase of the Henry Law Avenue and Payne Street Improvements. 

Henry Law Avenue is closed 24-hours-a-day from Washington Street to the parking lot for the Dover Indoor Pool. The left turning lane from southbound Central Avenue to Henry Law Avenue will be blocked by cones.

Henry Law Avenue will temporarily become a two-way street between George Street and the pool parking lot. All parking spaces on Henry Law Avenue will be temporarily eliminated during the first phase to allow two-way traffic.

Williams Street will be closed to through traffic and only accessible from the Central Avenue side.

The parking lot, Adventure Playground, Indoor Pool and Children's Museum of New Hampshire remain open throughout the project.

Some trees to be removed from Lower Henry Law Park; New trees to be planted

The contractor will remove a series of trees near the sidewalk of Lower Henry Law Park starting this week. New trees will be planted after work is completed. At the completion, Henry Law Park will have more trees then there are now.

The tree removal is necessary for underground utility work, including the installation of a new drainage system. The grade of the sidewalks will also be raised to the level of Henry Law Avenue. These actions would have killed or severely damaged the trees if left in place.
