Slow down to 35 miles an hour crossing the high span toward St. Armands right now, and you will notice two things. The first is the orange barrels squeezing traffic into a single lane near the Bird Key Drive intersection some nights. The second is that nobody around you seems entirely sure what any of it is for. Ask three neighbors and you will get three answers: they are widening the bike lane, they are fixing the drainage, they are just repaving because that is what road crews do every few years.
All three are technically correct, which is part of the problem. The Florida Department of Transportation's project on State Road 789, running from Bird Key Drive to Sunset Drive, bundles five separate pieces of work into one construction zone, and the piece getting the least attention is the one that actually explains why this project exists at all.
What the work covers, item by item
FDOT began construction on this stretch on December 28, 2025, with a stated project cost of $12.3 million and a targeted finish in early 2027. That puts the project at about eight months in as of this writing, with roughly five months of active work still ahead if the current estimate holds.
The scope, as FDOT has described it in project updates, breaks into five parts:
- Dedicated bicycle and transit lanes added to the bridge itself
- Drainage upgrades along the corridor
- Raising the seawall cap near Sunset Drive
- Resurfacing the roadway from Bird Key Drive to Sunset Drive
- New traffic signals installed at the Sunset Drive, Golden Gate Drive, and Bird Key Drive intersections
A sixth, smaller item: crews are relocating palm trees and shrubs from the eastern side of the causeway to medians closer to St. Armands Circle, which explains why a few stretches look temporarily bare.
Most of what residents notice day to day, the cones, the reduced speed, the occasional overnight lane closure, comes from the resurfacing and signal work. One example from earlier this year: FDOT closed the inside westbound lane at the Bird Key Drive intersection from 7 p.m. to midnight for a single night of repaving. That is the pattern for most of the disruption. It is loud, it is visible, and it is temporary.
The line item that actually explains the project
Bike lanes and repaving are the kind of upgrade a growing corridor gets on a normal maintenance cycle. Raising a seawall cap is a different category of decision, and it is the one that tells you why FDOT prioritized this stretch now rather than waiting another decade.
There is some history worth knowing here. John Ringling personally financed the original causeway in 1925, paying roughly $750,000 out of pocket, the equivalent of about $13.8 million in 2025 dollars, because he owned land on Lido and Longboat Key and needed a way to get buyers there. The bridge that exists today, the 65-foot span most people picture when they think of the Ringling Bridge, replaced an aging drawbridge in 2003 at a cost of $68 million. That drawbridge had been opening as often as 18 times a day and could no longer keep up with traffic. Every rebuild of this crossing, in other words, has been a response to whatever the previous version of the causeway could no longer handle. In 1925 that was access. In 2003 it was capacity.
This round is about water. Raising the seawall cap near Sunset Drive is not a cosmetic fix or a routine repaving line item. It is the corridor's answer to storm surge and rising tide lines on a stretch that sits low relative to Sarasota Bay. The bike lanes will get more attention because they are visible and they change how people move through the space every day. The seawall cap will matter more the next time a serious storm pushes water up against that section of road, which is exactly the kind of improvement that goes unnoticed until the day it is tested.
What's actually closed right now
If you are trying to plan around this rather than just white-knuckle through it, here is where things stand.
Sunset Drive has had a temporary closure at the Ritz entrance off Gulfstream Avenue to accommodate driveway reconstruction tied to the broader project, with FDOT estimating that closure would run about 60 days. If you use that entrance regularly, confirm current status before you rely on it, since these closure windows shift as phases wrap.
Speed limits on both Gulfstream Avenue and the John Ringling Causeway itself are reduced to 35 miles an hour for the duration of construction, and fines for speeding through the work zone are doubled when crews are present. That is not a suggestion. It is enforced.
Pedestrians and cyclists have their own detours. Bike lanes across the affected stretch have been closed intermittently during active phases, with posted detour routes for cyclists, and pedestrians are directed to designated paths rather than the usual sidewalk. Some visitors to Bird Key Park have noted the walking path underneath the bridge has been closed during active construction phases, which matters if that loop is part of your regular walk or run. If you rely on that route to get onto the bridge on foot, check conditions before you head out rather than assuming it is open.
Most of the heavier work, according to FDOT's own scheduling, happens during daytime hours, with occasional nighttime operations for tasks like milling and paving that are easier to do with lighter traffic. Expect noise from backup alarms and equipment during both windows.
Living with it until early 2027
None of this is unmanageable, but a few habits make it easier.
Build in extra time for anything routed through the Sunset Drive or Bird Key Drive intersections, especially in the evening when overnight lane work tends to start. If you walk or bike the causeway regularly, treat the posted detours as the current normal rather than a temporary inconvenience you can route around on your own. FDOT's project updates and detour notices are more current than word of mouth, and checking before a fishing trip to Bird Key Park or a bike ride toward St. Armands Circle saves you from finding a closed path in person.
The completion estimate is early 2027, and estimates like that tend to move a few months in either direction as phases finish or run long. Nothing about the six-month lookback since this project started suggests a dramatic acceleration or delay, which is about as much certainty as any active FDOT corridor project offers this far out.
What you get on the other side is a bridge with dedicated space for bikes and transit, better drainage, three modernized intersections, and a seawall cap built for the water levels this corridor is actually seeing now rather than the ones it was designed around in 2003. That is a meaningful upgrade to a crossing every Bird Key resident depends on, even if the version of it you are driving through this month is mostly cones and a 35 mile an hour limit.
If you are weighing what any of this means for property values or the long-term outlook on Bird Key, that is a different conversation, and one worth having with someone who tracks this market closely. Keith Curcio has been following Sarasota's barrier islands long enough to know which infrastructure work actually changes how a neighborhood lives day to day. Let's Connect if you want that conversation.
