Snake Creek's Hourly Lift Isn't as Settled as It Looks
Anyone who has timed a grocery run around the bridge at Mile Marker 86 knows the drill. Wait for the horn, watch the leaf go up, watch it come back down, then go. It feels like a fixture, something baked into the rhythm of Plantation Key the same way the tide is. It isn't. The schedule residents plan around was rewritten once already, in 2016, and this year marks the first time in almost a decade that the conversation about rewriting it again moves out of feasibility paperwork and into an actual environmental study.
Snake Creek Bridge is the only drawbridge still operating in the Florida Keys. It sits right where Venetian Shores meets the water, carrying US 1 over the creek that gives boaters in the neighborhood their shot at both Florida Bay and the Atlantic. Everyone who lives here has a relationship with it. Fewer people know how recently its rules changed, how often the posted schedule online is simply wrong, or how close FDOT is to finally starting the study that could replace it.
The bridge's current operating schedule is a federal rule, not a local custom. As of a 2016 final rule from the Coast Guard, Snake Creek Bridge opens on signal, except that from 7 a.m. to 6 p.m. it need only open on the hour. That replaced an older schedule that had been in place since 2001, when the draw opened on the hour and half hour between 8 a.m. and 4 p.m. FDOT and local officials asked for the change specifically to cut down on the vehicle backups those extra half-hour openings were causing, and the Coast Guard took public comment on it twice, first as a test deviation and then as a temporary interim rule, before making it permanent.
Here's the part worth knowing if you're timing a delivery, a contractor, or a ride to the airport around it: not every source agrees on what the current rule actually is. One widely used marina directory still lists the old 2001 schedule, hourly and half-hourly openings between 8 a.m. and 4 p.m., as if the 2016 change never happened. Another boater's guide splits the difference and lists an 8 a.m. to 6 p.m. window. The rule that's actually in effect, the one enforced by the Coast Guard and codified in the Code of Federal Regulations, runs 7 a.m. to 6 p.m., hourly only. Outside that window, the bridge still opens on signal, meaning a boat can hail the tender on VHF Channel 09 or sound one long and one short horn blast at 2 a.m. and the leaf goes up regardless of the clock.
The hourly rhythm is easy to take for granted until the bridge stops following it altogether. In September 2019, FDOT closed Snake Creek Bridge to vehicle traffic from 11:45 p.m. to 4 a.m., Sunday through Thursday, for three weeks straight, so a contractor could clean and paint the underside of the deck. The village pushed FDOT to move the start time back 45 minutes from its original 10:30 p.m. plan, a small concession that Mayor Deb Gillis said kept a bad situation from being worse.
The closure reached well past traffic cones. Islamorada Fire Chief Terry Abel described the burden on emergency transport plainly: "For us to transport south is a hike." Marathon Fire and Rescue Chief John Johnson said patients from Lower Keys Medical Center and Fishermen's Hospital who would normally go by ambulance would instead be flown to the mainland on Trauma Star helicopters for the duration. Then-Vice Mayor Mike Forster, who owns Mangrove Mike's, put the everyday version of the problem this way: "My opening cook and server come in at 5 a.m., and they come from over that bridge." Monroe County Sheriff Rick Ramsay opposed the closure outright, warning that his deputies would face real delays responding to calls on the wrong side of the bridge during those hours.
None of that was a malfunction. It was scheduled maintenance, cleared in advance, with public notice. The bridge doesn't need a mechanical failure to disrupt a night's plans. A repaint is enough.
Snake Creek Bridge has carried this distinction since 2008, when the drawbridge at Jewfish Creek in Key Largo was replaced with a high-span beam bridge and Marathon's Boot Key Harbor drawbridge was closed and abandoned the following year. Since then, every other moving span on US 1 through the Keys has been retired. This one hasn't.
The bridge itself dates to 1981, a single-leaf steel bascule span with a 27-foot vertical clearance when closed, and it's the fourth bridge to occupy that spot going back to an Overseas Railroad crossing built in the early 1900s. It's owned by FDOT but managed under Coast Guard rules, with a bridge tender under contract to FDOT and a Coast Guard waterways management station sitting right on Snake Creek itself. That's not a coincidence. This particular stretch of water gets enough traffic, boat and vehicle both, that having enforcement essentially on site has been the working arrangement for years.
Islamorada's Village Council first asked FDOT to look at replacing the bridge back in 2017, requesting a study into either a fixed span or a tunnel to relieve the traffic backups. FDOT agreed to a feasibility study, which cost around $200,000, and brought four possible replacement concepts to a public meeting at Founders Park Community Center in May 2019. None of the options landed well. Councilman Ken Davis argued FDOT should build a fixed span over Whale Harbor instead and lock the Snake Creek bridge down, since Whale Harbor already carries heavier boat traffic through a no-wake zone.
The feasibility study wrapped, and FDOT laid out the next steps: a scope report, an efficient transportation decision making screening, and then a full Project Development and Environmental study. FDOT's own timeline in 2020 put the scoping and screening work at 2024 and the PD&E study itself starting in 2025 or 2026. According to FDOT's current project tracker for the Snake Creek Bridge replacement, that PD&E study is scheduled to begin in 2026.
That's not the same as a new bridge breaking ground. A PD&E study is the phase where FDOT works through environmental review, traffic analysis, and design alternatives in enough detail to actually pick a path forward, and that process typically runs for years on its own. But after nearly a decade where "studying it" meant a completed feasibility report and not much visible movement, 2026 is the first year the project is scheduled to move into the phase that actually produces a decision.
None of this changes today's errand-timing math. The bridge still lifts on the hour between 7 a.m. and 6 p.m., still opens on signal outside those hours, and still occasionally closes without warning for reasons that have nothing to do with a malfunction, as residents learned in October 2022 when a gate issue backed traffic up from Mile Marker 82 to Mile Marker 91 before FDOT clarified crews had simply been out doing maintenance.
What's worth holding onto is that the current arrangement is a rule, one that got rewritten once already in 2016, not a permanent feature of the landscape. The PD&E study starting this year is the mechanism by which it could get rewritten again, on a much longer timeline than the last change but through the same basic process: a study, a public comment period, a decision.
For now, the horn still sounds on the hour, and the leaf still comes down. Whether that stays true for another eighteen years is now, for the first time since 2019, actually being studied rather than just discussed.
If FDOT's study produces public meetings or comment periods this year, that's the kind of local news I track closely and I'm happy to pass along what I hear. Reach out to Alina Davis anytime you want the plain version of what's actually happening at the bridge.
