Walk the loop from Island Park across the Ringling Bridge to Bird Key Park these days and you will hit a barrier where the path used to duck under the span. That underpass, the connector that let walkers and runners complete the loop toward Hart's Landing without ever touching traffic, has been closed since construction crews moved onto the bridge late last year. Most people treat that closure as an inconvenience to wait out. It is not. It is a preview.
The Florida Department of Transportation began work on State Road 789, the stretch of the John Ringling Causeway between Bird Key Drive and Sunset Drive, on December 28, 2025. The framing residents tend to reach for is "detour," as if the bridge will reopen looking the way it always did once the cones come down. It will not. FDOT is not patching this bridge. It is changing what the bridge does.
What's Actually Being Built
The scope, laid out on FDOT's SWFL Roads project tracker and echoed in updates from the Coalition of City Neighborhood Associations, goes well past resurfacing. The project adds dedicated bicycle and transit lanes to a bridge that has never had them. It raises the seawall cap near Sunset Drive. It installs new traffic signals at three intersections that currently rely on stop signs or informal right of way: Sunset Drive, Golden Gate Drive, and Bird Key Drive itself, the only signalized entry and exit points onto the island once the work is done. Crews are also relocating the palm trees and shrubs currently planted along the eastern stretch of the causeway to medians closer to St. Armands Circle, so the bridge will look different too, not just function differently.
That bike and transit lane detail matters more than it sounds. Today, a cyclist crossing the Ringling Bridge shares the travel lane with cars, which is exactly why the current construction detour for bikes exists at all: there is no separate lane to fall back on. When this phase finishes, there will be. The City of Sarasota has separately flagged a bus shoulder addition on the bridge for its free Bay Runner trolley, which will be permitted to use the shoulder once traffic slows to 15 mph or below, a detail worth knowing if you rely on the Bay Runner during season traffic.
Two Completion Dates, One Bridge
Here is something worth knowing that most residents checking a single source will miss. FDOT's own pages do not agree on when this finishes. The Coalition of City Neighborhood Associations, drawing on FDOT's project announcement, lists an estimated completion of early 2027. FDOT's own Sarasota County RoadWatch page, the one that updates week to week, currently reads "expected completion remains late 2026," while FDOT's districtwide RoadWatch page still shows "early 2027" for the same project. Neither has been corrected to match the other. The honest answer for anyone planning around this project is to expect the back half of 2026 through the first months of 2027, not a single fixed date, and to check the county RoadWatch page directly for the current week's status rather than relying on whichever estimate happens to be circulating.
What Changes Meanwhile
The posted speed limit through the corridor, on both Gulfstream Avenue and the causeway itself, holds at 35 mph for the duration. That number has not moved. What has changed is the cost of ignoring it: speeding fines double anywhere in the work zone when crews are present, a detail FDOT has repeated across every update since construction started. Lane closures come and go with the project's phase, sometimes daytime work, sometimes overnight, and noise from backup alarms, pumps, and power tools can carry after dark as well as during the day.
For anyone on foot or on a bike, the rule is simpler than the construction schedule: follow the posted detour, not memory of how the crossing used to work. Bike lanes on the bridge itself are closed for the duration, with a marked detour route. Pedestrians are routed to designated paths rather than the underpass connector, which is the barrier you will hit if you try to complete the old Island Park to Hart's Landing loop the way you always have.
Bird Key Park Is Still Bird Key Park
None of this touches the park itself. Bird Key Park, the small city-run waterfront park sitting right at the foot of the bridge, keeps its regular hours of 5 a.m. to 11 p.m. and its full run of uses: fishing off the seawall, kayak and paddleboard launches, and the leash-friendly water access on the south side of the bridge that makes it one of only a handful of spots on Sarasota Bay where a dog can wade in on a leash. What is temporarily gone is the ability to walk straight through, under the bridge, and continue the loop without a detour. The park has not shrunk. The connector through it has, for now.
That distinction is the one worth holding onto through the rest of this project. The causeway work is disruptive in the way any major bridge rebuild is disruptive, closures, noise, a longer walk around instead of under. But disruption and degradation are not the same thing. What's arriving on the other side of this timeline is a bridge with its first dedicated bike lane, its first dedicated transit shoulder, a raised seawall cap that accounts for water levels the 2003 bridge wasn't built around, and three new signals where informal right of way used to govern the flow on and off the island. The bridge that reopens will do more than the one that's currently torn up, which is a different proposition than simply putting it back the way it was.
If you're timing errands, a run, or a Bay Runner pickup around the Ringling Bridge this fall, check FDOT's Sarasota County RoadWatch page for the current week's specific closures rather than relying on a single estimate someone shared months ago. The project moves in phases, and what's posted this week is more reliable than what was posted in June.
For everything else happening on Bird Key, from how the island's single point of access is evolving to what that means for the daily rhythm of getting on and off, Kim Ogilvie and the team stay close to the details that actually affect life here, not just the ones that make headlines. Let's Connect.
