The Walnut Oval project in Nashua, New Hampshire, is a significant urban infrastructure initiative aimed at improving traffic flow, pedestrian and bicycle access, and overall connectivity to downtown Nashua. This project addresses the challenges posed by the existing large diameter circular intersection and aims to create a more efficient and safer environment for all modes of travel.
Understanding the Challenges
Walnut Oval is located on the west side of downtown Nashua and serves as a critical connection point for traffic coming from Veterans Memorial Parkway. The Parkway was intended to provide an alternative route to downtown Nashua, alleviating congestion on Main Street. However, the current configuration of Walnut Oval acts as barrier and has created safety concerns and inefficiencies for both vehicles and non-motorized users.
Our Vision for a Safer, Smarter Oval
The primary goal of the Walnut Oval project is to simplify the intersection and improve connectivity for vehicles, pedestrians, and cyclists. Key objectives include:
- Reducing the number of lanes to create space for on-street bike lanes, wider sidewalks, and green spaces.
- Enhancing pedestrian and bicycle infrastructure to ensure safe and efficient access through the intersection.
- Improving sightlines and reducing confusion for drivers by simplifying the circulation pattern.
- Creating recreational opportunities with a shared-use path in the center of the Oval.

Navigating Complex Needs
The project faces several design challenges, including:
- Balancing the needs of vehicular traffic with pedestrian and bicycle accommodations.
- Coordinating with existing businesses and residential complexes to ensure their parking and access needs are met.
- Managing the schedule demands associated with earmarked congressional funding, which requires certain portions of the project to be obligated by September.
Innovation at the Roadblocks
To address these challenges, the project team has proposed several innovative solutions:
- Reversing some of the one-way roadways to provide more direct routes to and from downtown Nashua.
- Implementing a compact roundabout design that allows large vehicles to track over the center, reducing the footprint and accommodating traffic flow.
- Designing the center of the Oval as a shared-use path that can be used for jogging and other recreational activities.
Collaborating with the Community
The project has involved extensive community engagement, including workshops where residents and local businesses could provide input on the design. This feedback has been incorporated into the Engineering Study and ongoing Preliminary Design efforts to ensure the project meets the needs of the community.
