Bridge Replacement Info

A new gateway for the Cape
bourne bridge

The Sagamore and Bourne bridges were built in 1933 and they changed the relationship between the Cape and the rest of Massachusetts. They allowed for cars to travel, enabling Cape residents to access jobs on the mainland while simultaneously launching a new tourism industry. Visit the US Army Corps of Engineers New England District Website to read more about the Cape Cod Canal History.

Today the bridges are nearly 90 years old and no longer meet the needs of the traveling public. The bridges must respond to today’s needs and expectations, which includes being brought up to modern/standard code, improving travel operations, and accommodating alternate modes of travel, such as biking and walking.

MassDOT Highway Division has started one of the most important transportation programs in the region: addressing the aging Sagamore and Bourne bridges and making improvements to the surrounding roadway networks. Please visit the MassDOT Cape Cod Bridges Program website for more information.  To contact MassDOT use email address:
