Cape Cod Bridges

Addressing the aging Sagamore and Bourne bridges and the surrounding roadway networks is one of the highest priority transportation improvements in the region.

The Sagamore and Bourne bridges are critical to the economy of Cape Cod and the surrounding communities. These bridges are more than 90 years old, functionally obsolete, require frequent maintenance, and no longer meet the needs of the traveling public.

The replacement of the Cape Cod Bridges will support the safe, efficient, and reliable movement of people, goods, and services across the Cape Cod Canal.
