U.S. Army Corps of Engineers Cape Cod Canal Bridges Major Rehabilitation Evaluation Study




Interested parties are hereby notified under provisions of the National Environmental Policy Act of 1969 (NEPA) (implementing regulations in 40 CFR 1500-1508 and 33 CFR 230), that the U.S. Army Corps of Engineers (USACE), New England District, has prepared a draft Major Rehabilitation Evaluation Report (MRER) and accompanying draft Environmental Assessment (EA) for the Cape Cod Canal Highway Bridges, Cape Cod Canal Federal Navigation Project, Bourne, Massachusetts.

Project Description:

The MRER is a decision document which will provide the basis for the Corps to determine the most cost-effective, safe, and practicable alternative for providing critical access across the Cape Cod Canal, a Federal Navigation Project (FNP). The Cape Cod Canal Federal Navigation Project consists of a channel, anchorages and other improvements that have been constructed and maintained by the USACE.  The draft MRER and accompanying EA evaluates alternatives to address component deficiencies of the Bourne and Sagamore bridges which impact their structural and operational reliability. The alternatives include, but are not limited to: continued repair and maintenance of the bridges as needed, perform a major rehabilitation, or replace both bridges with new structures. The MRER includes engineering, cost, economic, and environmental analyses. The Corps will address design and construction considerations and perform additional environmental analyses specific to the recommended plan in the next phase of the project.

Proposed Action:

Based upon recommendations of the MRER, the Corps proposes to replace both the Bourne and Sagamore bridges with new bridges consisting of a total of 4 travel lanes with 2 auxiliary lanes for each. New bridges would be built adjacent to the existing bridges and will incorporate modern safety design standards such as 12-ft. wide travel lanes; appropriate pedestrian and bicycle access with a separation barrier from vehicle lanes; a median between the two directions of vehicular travel; and shoulders to accommodate vehicle breakdowns. Bridge abutments would be located further north and south of their present locations on each side of the Canal in order to produce approach grades consistent with modern federal highway standards. The existing bridge piers are currently located within the Canal. New bridge piers would be relocated out of the water to the Canal shoreline.

The current bridges would remain open and continue to be inspected and maintained in a safe and reliable state while construction of the new bridges is underway. The current bridges would be dismantled after the new bridges have been opened to traffic. The actual bridge type, design specifications, and location of new bridges will be determined and evaluated during the design phase of the Cape Cod Canal Bridges Project, which is expected to occur after the MRER is approved.

Environmental Impacts:

The results, as found in the draft EA and Draft Finding of No Significant Impact (FONSI), show that the proposed action would not have a significant adverse impact on the environment. At the conclusion of the public comment period, it is anticipated a FONSI will be signed for the proposed action. An Environmental Impact Statement therefore, is not necessary to implement the Proposed Action for this phase of the Canal bridges project.

MassDOT Cape Cod Canal Transportation Study

This purpose of this conceptual planning study is to identify existing and future multimodal transportation deficiencies and needs around the Cape Cod Canal area.


The study entails developing and analyzing a range of transportation alternatives in Bourne and Sandwich. These include highway, interchange, and non-highway improvements, as well as options and design elements that improve access and safety for all modes. Additionally, this study includes significant coordination with the US Army Corps of Engineers on its study of the Bourne and Sagamore Bridges, which are under its stewardship and jurisdiction.
