A draft report released this week by the U.S. Army Corps of Engineers is recommending replacement of both the Bourne and Sagamore bridges.

The replacement project would cost $1 billion and is the preferred alternative to continuing to repair the bridges, which were built 84 years ago and are functionally obsolete, the draft evaluation by the Corps has found.

The two bridges span the Cape Cod Canal and provide access to Cape Cod, including the ferry ports to the two Islands in Woods Hole and Hyannis.

A series of public meetings have been scheduled by the New England District for the Corps this month on the Cape, in Plymouth and Boston. The first meeting will be held in Bourne on Oct. 16.

The Corps is inviting public comment on the draft report and assessment on its wesbite through Nov. 1.

A final report is expected in February 2020.
