Champeaux Road Bridge Replacement
The Champeaux Road Bridge, a 61-foot, three-span structure built in 1938, spanned Long Pond in Sturbridge, Massachusetts. Due to structural deficiencies, the bridge required a complete replacement. Utilizing leftover accelerated bridge project funding, the Massachusetts Department of Transportation (MassDOT) tasked CHA to design a replacement bridge that met MassDOT requirements.
The design resulted in a single-span, precast NEXT beam integral abutment bridge founded on micropiles as the replacement structure. An integral abutment bridge is typically chosen since it reduces long-term maintenance needs due to the elimination of joints at the ends of the bridges. Founding the bridge on micropiles minimizes the amount of materials required, increasing its cost-effectiveness. The new bridge enhances flood resilience, improves safety, and minimizes environmental impact.
At MassDOT’s request, CHA developed a structural monitoring plan to track the bridge’s performance. Our continuing research on this structure will inform future decisions regarding the installation of this cost-effective and minimally invasive bridge type.
Project summary
The replaced an aging three-span structure originally built in 1938.
We developed a three-year structural monitoring program to collect data on the bridge's performance.
Using 12.75-inch diameter micropiles reduced raw material needs and minimized disruptions.
