2025 ACEC-NH & NHDOT Technical Exchange Conference
Thursday April 17, 2025 2:00pm - 3:00pm EDT
Session 11A: Strafford Square Intersection (Rochester Roundabout)
Speaker: David McNamara, Stantec
- The Strafford Square intersection had long been one of the City’s highest priority transportation projects. The original layout created numerous conflict points leading to driver confusion and hesitation when traversing the intersection. The confusion distracted drivers from recognizing and responding to pedestrians and bicyclists, making it a dangerous and difficult area for all users.

The project included the construction of a modern multi-lane roundabout; relocating the aerial utility lines underground; new stormwater infrastructure including an underground infiltration system, water and sewer utility upgrades and replacements; and new ornamental street lighting, Rapid Rectangular Flashing Beacons (RRFBs), and landscaping.

Session 11B: Souhegan River Pedestrian Trail, Merrimack, NH
Speakers: Anna Giraldi, Turner Group; Tony Puntin, NHDOT
- The Souhegan River Pedestrian Trail connects the town’s four quadrants by providing a crossing of the heavily traveled US Route 3.  Utilizing an abandoned canal for a former shoe factory, the trail allows  residents and visitors  pedestrian access to the central business district, residential areas, parks, trails, shops, and schools, while maintaining the town’s history and environment. Although complex historical and environmental permitting requirements extended the design phase, construction was completed on time despite unexpected site conditions and will benefit the community for years to come. Innovative engineering solutions minimized environmental impact, including helical piles for the boardwalk to preserve the natural habitats and Foamed Glass Aggregate to reduce pressure on historic canal walls.
