薩加莫爾大橋（Sagamore Bridge）是連接科德角（Cape Cod）與麻州本島的關鍵通道，大橋設計包含兩座獨立橋跨，分別承載單向車流，以降低事故風險；還設有護欄隔離的共享路徑與景觀眺望點，以改善行人與自行車通行體驗，並強化橋墩設計，以因應科德角運河（Cape Cod Canal）的船舶交通需求。
麻州交通廳（MassDOT）表示，施工期間將維持雙向各兩車道通行，直至第一座新橋完工，並採用先進交通監測技術，與地方應變單位協調，減少尖峰時段衝擊。
奚莉州長強調，這是「數十年來首次真正落實的橋樑更新」計畫，將為地居民、商家與緊急應變系統服務。副州長Kim Driscoll指出，將持續與社區合作，確保施工管理得當。麻州代理交通廳長兼MBTA總經理伍偉華（Phillip Eng）與公路局長強納森·古利佛（Jonathan Gulliver）都表示，設計過程將納入公眾意見，打造符合科德角風貌的基礎設施。
根據時程，工程將於2027年底發佈開工通知，2028年春季正式動工；2033年所有車流改行新橋，2036年全案竣工。施工期間，官方將透過專屬網站定期更新交通狀況，並與伯恩鎮及緊急服務單位密切配合，確保事故快速排除及主要設施聯通。
薩加莫爾橋與伯恩橋（Bourne Bridge）同為1930年代啟用的橋樑，是科德角半島對外僅有的兩條陸路通道，此次改建為麻州近年最大規模的跨運河基建投資，州政府將陸續公佈總經費與細部預算。
Governor Healey Unveils New Design Renderings for Replacement Sagamore Bridge
New designs showcase safer travel, improved pedestrian and bicycle access, and continued progress on replacing the aging Cape Cod bridge
BOURNE — The Healey-Driscoll Administration today unveiled new design renderings of the replacement Sagamore Bridge, giving residents, businesses and visitors a detailed look at the future bridge as Massachusetts continues making historic investments to replace the aging Cape Cod Bridges. The new renderings showcase key design features, including separate bridge spans to improve safety, a barrier-separated shared-use path for pedestrians and bicyclists, upgraded roadway connections, and architectural features that reflect the character of the region.
"For decades, people have talked about replacing the Cape Cod Bridges. Our administration is getting it done," said Governor Maura Healey. "These new renderings give people a look at the safer, stronger bridge we're building for residents, businesses and everyone who depends on these crossings every day. We're making historic investments to improve transportation, strengthen the Cape's economy and make it easier and safer for people to get where they need to go."
"These bridges are essential for Cape Cod families, local businesses, first responders and millions of visitors every year," said Lieutenant Governor Kim Driscoll. "As this project moves forward, we're continuing to work closely with local communities so construction is managed responsibly while delivering infrastructure that will serve the region for generations."
“These new renderings allow residents, businesses, and communities across the region to begin seeing what the future of this vital transportation connection will look like,” said Interim Secretary of Transportation and MBTA General Manager Phillip Eng. “Replacing the Cape Cod Bridges is a once-in-a-generation investment in the safety, reliability, and economic future of Cape Cod, the Islands, and the surrounding region. As the project advances, we remain committed to listening to the public, addressing community concerns, and delivering an innovative, high-quality design that will serve generations to come.”
“MassDOT hopes these new renderings help people envision how the new Sagamore Bridge will improve safety, enhance mobility, and meet the region’s transportation needs for generations to come,” said Undersecretary of Transportation and State Highway Administrator Jonathan Gulliver. “As the design continues to advance, MassDOT looks forward to incorporating public feedback to help shape a final design that reflects Cape Cod.”
The Sagamore and Bourne bridges are more than 90 years old and carry more than 38 million trips each year, serving as critical connections for residents, businesses, visitors and emergency responders. Through the Cape Cod Bridges Program, the Healey-Driscoll Administration is replacing these aging bridges with safer, more reliable and more resilient infrastructure while improving connections to local roadways and reducing congestion.
The new renderings highlight several major improvements, including twin bridge spans carrying one direction of traffic each to improve safety, a barrier-separated shared-use path with a scenic overlook for pedestrians and bicyclists, enhanced lighting, and bridge foundations designed to better accommodate marine traffic through the Cape Cod Canal.
During the public hearing, MassDOT also provided an update on construction phasing and traffic management. Throughout construction:
• Two lanes in each direction will remain open until the first new bridge span is complete.
• The project team will use advanced traffic monitoring technology, coordinate closely with local officials and emergency responders, and limit construction impacts during peak travel periods to help keep people moving safely.
MassDOT will coordinate closely with the Town of Bourne and Bourne emergency services to ensure quick clearance of incidents and access to key facilities and the Cape Cod Bridges website will feature regular updates on traffic conditions during the construction phase.
Construction is expected to begin in spring 2028 following a Notice to Proceed in late 2027. All traffic is expected to be traveling on a new bridge by 2033, with final completion currently anticipated in 2036.
