"This is an icon of our community." That's how James Stock, the Sarasota County engineer who inspects the bridge for a living, described the one-lane swing span that most people who live on Casey Key cross without a second thought. The Blackburn Point Bridge carries Blackburn Point Road over the Intracoastal Waterway, right past Blackburn Point Park, the tiny Casey Key Library, and the tiki bar at Casey Key Fish House. It has done that job since December 1926, which means it turns 100 this winter.
The county was supposed to decide its fate around the same time. A formal hearing before the Sarasota County Board of Commissioners has been tentatively penciled in for this fall, the point at which the county's multi-year study of the bridge finally gets a public vote. As of mid-September, no date had been set. And two weeks before this post went up, a new number entered the debate that complicates the story locals thought they already understood.
The argument on Casey Key was supposed to be preservation against safety. The new numbers turned it into something narrower and stranger: nobody can agree on what preservation itself would cost.
A Bridge Built for Model Ts
Stock has been blunt about why the county wants to move on from the current structure. The bridge was engineered for a 50-year service life. It has already run twice that. Its travel lane is 16 feet wide with no shoulders, no sidewalks, and no bike lane, and its clearances over the water sit at roughly half of what the U.S. Coast Guard recommends for a waterway like this one.
His comparison for why a 1926-era design struggles with 2026-era traffic is the kind of detail that sticks:
"Vehicles in 1926, I think it was something like only 33% of people in Florida actually owned a vehicle, and that the typical vehicle was a Model T, which was much lighter than the traffic that it's carrying now."
That's the county's core argument in one sentence. The bridge was never built for the weight, width, or frequency of the traffic crossing it in the 2020s, and the corrosion inspectors have documented for years is now compounding on itself. Stock has described it more plainly elsewhere: repairs are needing repairs.
Three Meetings, Still No Vote
This hasn't happened in a single public hearing. The county has been building its case, and hearing objections to it, in stages:
- August 19, 2025 — the first informational meeting on the Project Development and Environment (PD&E) study, held at Church of the Holy Spirit in Osprey
- November 12, 2025 — a second public meeting, same format
- June 11, 2026 — a third open-house meeting, where the county laid out the alternatives still on the table: keep the existing bridge and repair it, build a new one-lane or two-lane swing span, or build a bascule bridge instead
By last year, the county had already reported spending more than $200,000 on repairs to the bridge over the prior four years. None of that spending fixed the underlying problem. It bought time.
The Number Gap
Here is where the story stopped being simple. In June, Stock told reporters that if the county chooses to keep the bridge and renovate it, the work would cost an estimated $31 million. That figure has been the county's working number for the "no-build" option ever since.
Then, on September 13, the Sarasota Alliance for Historic Preservation released a competing analysis. The group, which placed the bridge on its 2025 "Six to Save" list of endangered historic resources, commissioned a review from Bach Ornamental & Structural Steel, a Michigan firm that specializes in restoring historic bridges. That review looked at the county's own inspection records, photographs, and cost estimates and arrived at a very different total.
| Estimate | Source | Scope | Total |
|---|---|---|---|
| County estimate | James Stock, Sarasota County, June 2026 | Rehabilitate existing bridge | $31 million |
| Independent review | Bach Ornamental & Structural Steel, commissioned by SAHP, September 2026 | Rehabilitate existing bridge (2028) plus maintenance through 2043 | About $17 million total |
Both numbers describe the same option: keep the bridge and fix it. They land nearly $14 million apart. SAHP co-president Jan Vertefeuille has said the group intends to keep pushing that gap in front of commissioners, calling the bridge a source of community pride and arguing that a thoughtful restoration looks cheaper than the county's replacement math suggests. Nearly 2,000 residents have already contacted the commission or signed petitions asking that the span be saved, according to the group.
What Actually Sits Next to the Bridge
Part of why this argument runs hot on Casey Key is what's physically clustered around the crossing. Blackburn Point Park sits right at the water's edge. The Casey Key Library, a small branch that many residents treat as a neighborhood fixture, is a short walk from the bridge deck. Casey Key Fish House, the boat-up seafood spot on Blackburn Point Road that's been serving the island since 1997, backs right up to the water the bridge swings over.
County officials have said displacing those businesses isn't the goal of any replacement design, but the concern hasn't fully gone away among people who use that stretch of road daily. The bridge is also the only vehicle link connecting the north end of Casey Key to U.S. 41, which puts it on the county's list of evacuation routes. Officials have pointed out that the current width creates real risk if a single vehicle stalls on the span during a storm evacuation, since there's no way for traffic to go around it.
What Happens This Fall
The mechanics from here are straightforward, even if the outcome isn't. Once the Board of Commissioners holds its hearing, tentatively slated for this fall, the PD&E study moves forward with whatever direction the board provides. That could mean picking a preferred alternative outright, or sending staff back for more analysis given the new cost figures now in front of them. As of mid-September, the county had not made a final decision, and no hearing date had been announced.
SAHP has said it plans to keep advocating for rehabilitation regardless of how the timeline shifts. Because the bridge is listed on the National Register of Historic Places, any project involving federal funding would also trigger federal historic-preservation review, which is its own layer that could stretch the process further.
Whatever the commission decides, the crossing that residents have used to reach the Fish House, the library, and the park at the north end of the key for a century is heading into its most consequential year yet at exactly the moment it's celebrating its 100th.
If you live on Casey Key and want your name attached to the record before the commission votes, the county is taking public comment through its project page and by email at [email protected]. I follow projects like this one closely, not because they show up on a listing sheet, but because they shape what daily life on the key actually looks like for the next hundred years. If you'd like to talk through what a decision like this could mean for a specific property near Blackburn Point, Victoria Turner is a call away.
