On Monday, the Massachusetts Department of Transportation (MassDOT) unveiled the recommended designs for the new Bourne and Sagamore bridges in Cape Cod. The layouts aren’t finalized, but the designs are the top choices from MassDOT.
On the Cape Cod side of the Bourne Bridge, a diamond-shaped interchange would eliminate the rotary. On the north side, flyover ramps would separate local traffic from regional traffic.
On the Cape Cod side of the Sagamore Bridge, MassDOT is recommending an extension of Cranberry Highway and a new Sandwich Road Connector to keep local traffic flowing. On the north side of the bridge, the layout would offer a direct connection to State Road.
A simulated video flyover of the new Sagamore Bridge showed the homes east of Eleanor Avenue, on the Cape side of the bridge, demolished and replaced with grass and trees.
The state’s recommendations for each interchange won’t officially be the “preferred” options for planning purposes until after MassDOT files a draft environmental report with the federal government in the spring.
The Sagamore Bridge will be built first, with the Bourne to follow when the state can win federal funding.
Funding for the approximately $2.13 billion cost of the Sagamore is almost complete, with a mix of federal grants, federal budget funds and a state contribution.
Construction will start on the Sagamore sometime after the state approves it, which is likely to happen in late 2027 or early 2028. The construction work is expected to last about six years and could be done in 2034.
