Drive over the Sagamore Bridge this summer and you'll see it: a tall crane parked near the old Christmas Tree Shops site, some fencing, workers in vests. It looks like construction has started. It hasn't. What's happening under that crane is soil testing, not bridge building, and the fact that so many people mistake one for the other says something about how this project actually moves. The visible activity on the ground is the least important signal. The real changes this year happened in paperwork, in a courtroom-adjacent process called eminent domain, and at a public hearing inside Bourne High School, not at the construction site.
If you live in Bourne, you've probably absorbed some version of "they're finally replacing the bridges" as background noise for years. What's different in 2026 is that the project crossed from planning into something closer to irreversible, even though actual bridge construction is still roughly a year and a half away. Here's how to tell the difference between motion and progress, and what each piece of this actually means for your daily life on the canal.
The Crane Is Testing Soil, Not Building a Bridge
MassDOT began its foundation load testing program on May 1, 2026, drilling shafts and driving piles at four locations near the current Sagamore Bridge, two north of the canal and two south. The work south of the bridge started first, in the area of the former Christmas Tree Shops. If you've heard loud banging near the canal this year, that's pile driving, not the start of the new bridge. It will generate data MassDOT needs to design a foundation strong enough to hold the future span, and it will not affect traffic.
That distinction matters because it's easy to read heavy equipment as a start date. It isn't one. The equipment is there to answer an engineering question. The actual answer to "when does construction start" came from somewhere else entirely: two regulatory approvals that cleared this spring and summer.
What Actually Unlocked This Year
On April 17, 2026, the Massachusetts Environmental Policy Act office issued a certificate on the Final Environmental Impact Report for the Cape Cod Bridges Project, closing out the state's environmental review. In June 2026, the Federal Highway Administration approved the project's Final Environmental Impact Statement and issued a Record of Decision, concluding the federal review under the National Environmental Policy Act. Those two approvals, not the crane, are what actually moved this project forward this year. Environmental review is often where infrastructure projects stall for a decade. This one didn't.
With that cleared, MassDOT moved into procurement. By April, the agency had formally launched the process to select a design-build contractor for the Sagamore Bridge, hosting an industry day that drew strong interest from regional and national firms. Roughly $1.2 billion in federal grant funding is expected to transfer to state accounts once that phase advances. A Notice to Proceed with the winning contractor is expected in late fall 2027, with construction beginning that winter or the following one.
Here's the part that surprises people who assume "the bridges" are moving as one project: they aren't.
| Sagamore Bridge | Bourne Bridge | |
|---|---|---|
| Funding | $1.72 billion secured federal funding plus $700 million committed state funding | Federal grant application still under review |
| Environmental review | FEIR certified April 2026; federal Record of Decision June 2026 | Not yet at that stage |
| Current activity | Foundation load testing underway since May 2026 | Army Corps of Engineers maintenance only |
| Construction start | Winter 2027/2028 | Not yet scheduled |
The Sagamore Bridge is fully funded and moving through procurement. The Bourne Bridge is still waiting on a federal funding decision, with the Army Corps of Engineers doing interim maintenance to keep the 90 year old structure functional in the meantime. If your mental model has been "they're building two new bridges," the more accurate one for 2026 is "they're building one bridge, with a second one queued up behind it."
Round Hill's Second Time Around
The part of this project that has actually changed daily life for specific families is eminent domain. Thirteen homes, mostly in the Round Hill neighborhood, and three commercial businesses are being taken to make room for the new Sagamore Bridge's approach. MassDOT started sending notices early in 2026, well ahead of construction, because the agency wanted to give people time to work through the appraisal and negotiation process without feeling rushed.
Not everyone had time to plan around it. Joan and Marc Hendel bought their Round Hill property in 2023 and finished building a new home there at the start of 2026, according to assessor records, without knowing the state's plans would take it. At a public meeting, Joan Hendel asked why there was no mental health support for residents facing the loss of their homes. Her words: "It puts us over the edge."
For longtime Bourne residents, this isn't the town's first experience with land takings for infrastructure. Jerry Ellis, a 91 year old lifelong resident, former selectman, and superintendent of Sagamore Cemetery, points back to 1904, when construction of the Cape Cod Canal itself demolished around 25 homes and relocated roughly 10 more, including the home of the Bourne family the town is named after, and required moving two cemeteries. In the 1960s, the state took more than 100 properties in Taylor's Point when the Massachusetts Maritime Academy expanded, among them the home of current selectman Peter Meier's grandparents. And when the Sagamore Rotary was replaced with the flyover ramp system between 2006 and 2007, the Bourne Chamber of Commerce lost its visitor center, the Sagamore Fire Station relocated down the street, and the Sorenti Brothers gas station eventually won a $5.3 million verdict over the taking of its Shell station and convenience store.
Meier's read on the current round, having lived through the last one: "We are a very resilient community. We've been through a lot, and we will persevere, and we'll be a better community for it."
The Detour That Almost Wasn't
The other place where this project already touches daily life, regardless of whether you own a car, is the Canal Service Road, the paved path that runs along both sides of the canal and doubles as the region's most-used bike and walking route. It's officially an Army Corps of Engineers access road, but it functions as Bourne's shared backyard trail, connecting the Buzzards Bay, Herring Run, Bourne, and Tidal Flats recreation areas.
MassDOT's original construction plans didn't fully account for how much residents rely on that stretch of path. That changed after pressure from residents and Bourne's Conservation Commission chair, Robert Gray. At a July 23, 2026 hearing at Bourne High School, MassDOT unveiled a revised detour plan: on the Cape Cod side, the path will route from Keith Field to Sandwich Road before reconnecting near the Mid-Cape Connector, and on the mainland side, it will follow Canal Street and Scenic Highway to the Herring Run Recreation Area. Luisa Paiewonsky, MassDOT's executive director of megaprojects delivery, put it plainly at the hearing: "We weren't aware of how important that stretch of Canal Service Road was to Bourne residents. So, by coming here and hearing you out, that brought us to a better conclusion."
That detour isn't a someday problem. A quarter mile of the Canal Service Road under the Sagamore Bridge on the mainland side has already closed for construction safety, and MassDOT has said bike path users may need to route around construction for nearly a decade. If you ride, walk, or fish that stretch regularly, this is the year the map actually changed, not some future year when the new bridge opens.
The Timeline, Actually
Strip away the crane and the paperwork and here's where the calendar stands. Construction on the new Sagamore Bridge is expected to begin in the winter of 2027 or 2028. The southbound span could open to traffic around 2033, with the northbound span following a little more than three years later. Both existing bridges are expected to stay open and carry traffic through the entire build, since the new spans are being constructed alongside the old ones rather than in their place. The Bourne Bridge has no construction date at all yet, since it is still waiting on the federal funding decision that would put it on a comparable track.
Local officials have also said construction will pause during peak travel periods, including around the Fourth of July, and that new lane widths and a barrier-protected shared-use path with a scenic overlook near the midpoint of the bridge are part of the design MassDOT presented this year.
What To Watch Next
If you want to track this project accurately rather than reactively, the milestones that matter aren't visible from the road. Watch for MassDOT's contractor selection, expected around the end of 2026, which will be the next real confirmation that the winter 2027/2028 construction start is holding. Watch for whether the Bourne Bridge's federal funding application clears review, since that decision determines whether Bourne ends up managing one bridge replacement or two running in parallel. And if you use the Canal Service Road, watch for the detour signage itself, since MassDOT has said the rerouted path will be built out well before construction reaches that stretch.
None of this is happening quickly. But some of the parts that used to feel indefinite (the funding, the environmental review, the actual route your bike ride will take) got a lot more concrete this year. That's worth knowing whether you're planning a commute, a ride along the canal, or simply trying to understand why your neighbor in Round Hill is working through the appraisal process this year.
