Heavy traffic, poor sightlines, skewed side streets, and uncontrolled driveways plagued the southernmost segment of NH Route 125 with numerous crashes and traffic congestion. Plans to improve this heavily traveled, regionally significant corridor have been an ongoing effort—spanning 20 years. In 2017, the fourth of five construction projects was completed, which improved the southernmost segment of the NH125 Plaistow-Kingston project.
In addition to roadway improvements, the $7M construction project involved complete streets-oriented improvements, such as ADA-compliant sidewalks, widened shoulders, and medians with low-height landscaping. These enhancements encourage non-motorized travel, benefiting public health while reducing vehicular traffic. With its access management solutions and waterline improvements, the project also bolsters immediate and long-term potential for economic growth along this corridor, which is already laden with retail and commercial businesses. The project was also composed of numerous innovative and first-in-the-state traffic and environmental solutions, including the U-Turn signal phases used at the intersection of NH 125 and Access Drive, and a Corridor-Wide Emergency Spill Response Plan.
