About this Project
When FST designed the landmark Sagamore and Bourne Bridges in the mid-1930s, a trip to Cape Cod was a pleasurable outing. But for many years travel to the Cape has meant contending with massive summertime traffic jams. The antiquated Sagamore Rotary at the north end of the bridge caused a significant portion of the backup. MassDOT looked to replace the Rotary as a key to alleviating these perennial traffic jams.
FST assisted in refining the Preferred Alternative replace the Rotary with a grade separation of local and regional traffic movements. The grade separation reduced delays, improved air quality by limiting congestion, enhanced safety by minimizing conflicting movements, improved local access for the business community; and improved bicycle and pedestrian safety.
Key to the success of this high-visibility project was developing the plans in close cooperation with the local community, Chamber of Commerce, and local businesses, long concerned about diverting bridge-bound traffic from their doors. The grade separation eases access and enhances the safety of their potential patrons.
FST’s responsibility on the design was highway, bridges, drainage, and ITS elements. FST prepared a 25% level of completion design in support of preparation of the EA/EIR, and then completed final design and construction phase services.
The project required detailed and complex traffic staging sequences to make the gradual transition from the old Rotary to the new, grade separated interchange.

The rotary, about 50 miles south of Boston, was long considered one of the worse intersections in the state, a choke-hold that could back up Cape-bound traffic for miles on the worst travel days of the year. By doing away with it, state officials, local residents, and those who summer on the Cape say the state managed to both improve traffic flow and the quality of life in a place where good living is especially prized.
“You’d live in fear –you’d live in mortal fear – of being caught in traffic for 45 minutes at that spot,” said Steve Grossman, a former Democratic National Committee chairman who lives in Newton, owns a home in Centerville, and often makes the drive back and forth to Boston in the summer. But now? “It’s lovely. I can’t tell you how much it’s changed people’s quality of life in terms of Cape travel.”
