MassDOT filed the Draft Environmental Impact Statement (DEIS) for the replacement of the Cape Cod Bridges under the National Environmental Policy Act (NEPA). The DEIS represents a significant milestone in the advancement of the Cape Cod Bridges and is now available for public review and a 45-day public comment period through January 5, 2026.
The public is invited to visit the interactive summary site to view the DEIS in an interactive format, learn about the proposed improvements, and review key findings. A PDF version of the chapters, sections, and appendices that make up the DEIS can also be found online. Public comments can be submitted through the interactive summary site or through the online comment form.
A DEIS public hearing will also be held at the Admiral’s Hall at Mass Maritime Academy on December 16, 2025, at 6 p.m. At this public hearing, MassDOT will provide information and key takeaways and accept public comment.
Additional environmental details are available on the Environmental page.
Borings program
MassDOT is currently conducting subsurface investigations and related vegetation management operations alongside state highways and on US Army Corps of Engineers (USACE) property in areas north and south of the Sagamore Bridge in Bourne.
These borings involve drilling into the ground to extract soil samples. MassDOT will analyze the samples to learn about subsurface conditions such as soil strength and composition. This information is critical to designing safe and durable bridge components and related infrastructure nearby.
This work will enable future construction operations and is an example of MassDOT's commitment to advancing the Program efficiently and effectively. These critical activities represent some of the first early action items for the Cape Cod Bridges Program. MassDOT will continue to provide public updates as the borings work continues.
