What’s Being Built on the Treasure Coast Right Now
Drive any major road between Vero Beach, Port St. Lucie, or Stuart, and the cranes, barricades, and freshly graded lots tell you something. Our region is in the middle of a building cycle and infrastructure upgrade, unlike anything it has seen in decades.
From a brand-new I-95 interchange in Indian River County to a luxury motorsports community rising out of St. Lucie County's western farmland, the Treasure Coast is being reshaped in real time.
Here is a county-by-county look at some of the projects that are underway or on the verge of breaking ground.
Indian River County: New Door on I-95
The Oslo Road Interchange
The most significant infrastructure project currently under construction in Indian River County is the new I-95 interchange at Oslo Road, and it is moving faster than expected.
The total cost of this project is $95 million, with Indian River County contributing $6 million, the state of Florida providing $28 million, and federal funds adding $61 million. Construction began in August 2023, and the project is currently ahead of schedule.
Oslo Road is a major east-west corridor in the county, connecting rural farmland, growing suburban neighborhoods, and the Indian River Lagoon. For years, residents in the southern part of the county had no direct access to I-95 without driving north or south to an existing interchange. That changes with this project.
The implications go beyond convenience. The interchange is expected to take the burden off drivers during hurricane evacuations, according to Commissioner Joe Earman, which was a major selling point in getting the project done. The county also recently voted to expand its urban service boundary around the new interchange, opening the door to future commercial and residential growth in the corridor, though a one-year moratorium on rezoning was imposed to allow for careful planning.
The project is expected to be completed in early 2027.
Martin County: The Brightline Question
A Station in Limbo
No project better captures Martin County's growth tensions than the proposed Brightline station in Downtown Stuart, and right now, its future is genuinely uncertain.
Nearly two years after Brightline announced Stuart as the location for its next high-speed rail station, the project remains in limbo as Martin County pursues federal grant funding for the second time.
The backstory: The Federal Railroad Administration did not approve Martin County's request for $45 million in grant money last year. That funding was expected to cover most of the project's $60 million cost, with the remaining $15 million to be covered locally. The federal program was then restructured entirely, forcing the county to reapply from scratch.
The costs have since grown. The total estimated cost for the project is now $87.15 million, up from $60 million in 2025, with Martin County contributing a non-federal cost share of $17.87 million, which includes $15 million in bond financing and $2.87 million in land value.
Even if all goes as planned, the Stuart station would not be ready until the spring of 2029, later than previously hoped. The county is awaiting a decision on its latest grant application, expected sometime this summer.
There is also a political dimension. Stuart Mayor Christopher Collins has expressed reservations about the project from the beginning, with his preference being that Brightline pay for half of the station. Notably, the city of Stuart did not include a letter of support in the county's latest federal grant application.
For now, Brightline trains pass through Stuart without stopping. Whether that changes depends on decisions being made in Washington.
SR-714 Widening
Separately, FDOT's State Road 714/SW Martin Highway widening project is the only active FDOT construction project currently listed for Martin County. It is a quieter but locally significant road improvement for residents in the western part of the county.
St. Lucie County: Building at Scale
P1 Motor Club
The most unusual project on the Treasure Coast right now is also the most ambitious. P1 Motor Club broke ground last year on a facility in western St. Lucie County that is described as the state's largest motorsports project ever.
The 650-acre site is comprised of three distinct areas: the P1 Members' Club with a 4.5-mile P1 Circuit, Clubhouse, and Residential Community; the Treasure Coast Motorsports Complex with a 3-mile circuit, karting circuit, rally circuit, and drift circuit; and P1 Commerce Park.
It is not just a racetrack. The facility will also integrate residential elements, offering condominiums and customizable garages equipped with living spaces.
The company plans to open the P1 Circuit in the first quarter of 2026 for member-only driving, with private garages and residences to become available during the second quarter of 2026. The commerce park side of the development is already drawing interest: more than half of the 400,000 square feet set aside for the commerce park has already been reserved, with future tenants including prominent race teams and car-prep shops.
Tradition Keeps Growing
The Tradition corridor in Port St. Lucie continues to add retail and commercial anchors. Construction of a 134,000-square-foot Lowe's store at the Shoppes at Southern Grove is underway, with a projected opening in 2026. The surrounding area has over 38,000 new homes planned for development.
A larger mixed-use project is also proposed for the northeast corner of SW Village Parkway and SW Becker Road, with plans calling for 660 residential units, nearly 200,000 square feet of commercial space, and a 140-room hotel. That project, from the Sansone Group, is still awaiting final city approvals.
Growing Pains in St. Lucie Gardens
Not everyone is celebrating. As construction ramps up across St. Lucie County, neighbors in the St. Lucie Gardens area are urging commissioners to slow down approvals and protect their way of life. St. Lucie County Commissioner Jamie Lee Fowler noted that many of the developments were approved years ago and are protected under state law, saying development can stay alive for about 20 years with proper extensions.
It is a dynamic familiar to anyone watching growth on the Treasure Coast: projects approved long ago are finally going vertical, often in neighborhoods that have changed considerably in the decades since the original approvals.
The Big Picture for Treasure Coast Residents
What ties all of this together is pressure, population pressure, traffic pressure, and economic pressure. The Treasure Coast is no longer a slow-growth outlier in Florida. The projects listed above represent billions of dollars in public and private investment arriving in a compressed window, and more are in the pipeline.
For residents, the honest answer to "what's being built?" is: a lot, fast, with varying degrees of local support. Some of these projects like the Oslo Road interchange address infrastructure deficits that are decades in the making. Others like P1 Motor Club represent an entirely new kind of development for a region that has historically resisted large-scale change. And the Brightline question remains genuinely open, with real consequences for downtown Stuart and the region's long-term connectivity.
The cranes are up. The outcomes are still being written!
