The project involves replacing the aging Route 27 bridge over Route 9 with two single-span bridges and adding a dedicated bridge for pedestrians and cyclists. The redesigned interchange aims to enhance traffic flow and reduce collisions by eliminating left turns across oncoming traffic, potentially cutting vehicle-to-vehicle accidents by up to 50%. The project also includes accessible bike and pedestrian facilities along Route 27, from Rutledge Road in the north to Bacon Street in the south, and upgrades to 3,600 feet of Route 9, including drainage improvements and median barrier replacements.
Jacobs and McCourt Construction will utilize Jacobs’ StreetLight mobility analytics platform to monitor traffic patterns and minimize disruptions during construction. The cloud-based tool analyzes real-time data from connected devices to provide insights into traffic movement and safety needs. The platform will also guide the placement of shared-use paths connecting to nearby schools, transit hubs, and major employers, fostering community connectivity.
Katus Watson, executive vice president at Jacobs, highlighted the project’s significance: “The Natick Bridge replacement, a first-of-its-kind interchange in Massachusetts, exemplifies how infrastructure and data solutions together deliver lasting societal benefits.” Watson added: “Using insights from our StreetLight platform, we’ll keep traffic moving while delivering an innovative interchange design that improves safety and strengthens community connectivity.”
The diverging diamond interchange design is expected to alleviate congestion and enhance safety at the busy intersection. By integrating modern infrastructure with data-driven planning, the project will support Natick’s growing transportation needs while prioritizing accessibility and sustainability. Jacobs anticipates completing the project by mid-2030, delivering a safer and more efficient transportation network for the region.
