Simpson Bay Bridge Schedule 2026 and How to Beat the Traffic
The Simpson Bay Bridge opens seven times a day on a fixed schedule, and every time it opens for boats, all car traffic across it stops for roughly 10 to 20 minutes. If you are heading to the airport, back to your cruise ship, or across the island for a tour, getting caught on the wrong side of an opening is one of the most common ways people run late in St. Maarten. Below are the 2026 opening times and how we plan around them.
For getting between the port and the west end of the island, pair this with our cruise port guide and our taxi rates guide.
Key Takeaways
- The Simpson Bay Bridge opens 7 times a day: 8:30, 9:30, 10:30, 11:30 AM, then 2:00, 4:00, and 5:00 PM.
- Each opening closes the road for about 10 to 20 minutes, plus the traffic backup that follows.
- The bridge is the main link between the airport, Maho, and Simpson Bay on one side and Cole Bay and Philipsburg on the other. When it opens, that whole corridor stalls.
- Build a 30 to 45 minute buffer around any opening when you have a flight or an all-aboard time.
- The Causeway Bridge is a separate crossing with its own schedule, so it can be a backup route, but check both before you rely on it.
What is the Simpson Bay Bridge?
The Simpson Bay Bridge is a drawbridge that connects the open sea to the Simpson Bay Lagoon, one of the largest inland lagoons in the Caribbean and home to several marinas and superyacht docks. When a boat needs to pass between the sea and the lagoon, the bridge swings open, and while it is open, no cars can cross.
That matters to visitors because the bridge sits on the main road through Simpson Bay, right between the airport and Maho on one side and Cole Bay and Philipsburg on the other. There is no quick way around it on that route. When the bridge opens, traffic in Maho, Simpson Bay, and Cole Bay backs up, and it stays backed up for a while after the bridge closes again.
The 2026 Simpson Bay Bridge schedule
The bridge runs on a published daily schedule. "Outbound" means boats leaving the lagoon for the sea, and "inbound" means boats coming in from the sea. For you as a driver, the direction does not matter. What matters is that the road closes at each of these times:
| Opening time | Boat direction |
|---|---|
| 8:30 AM | Outbound |
| 9:30 AM | Inbound |
| 10:30 AM | Outbound |
| 11:30 AM | Inbound |
| 2:00 PM | Inbound |
| 4:00 PM | Outbound |
| 5:00 PM | Inbound |
These times are set by the local port authority and were current as of mid-2026, but they do change. The afternoon openings in particular were adjusted at the end of 2024 to ease traffic through Maho and Cole Bay, and the schedule can shift for weather, holidays, or events like the Heineken Regatta in early March. The posted schedule can slip, so give yourself margin.
How long does an opening actually last?
The bridge itself is usually open for 10 to 20 minutes per cycle, depending on how many boats are waiting to pass. The wait is longer than those minutes suggest. Once dozens of cars have been sitting still on a two-lane road, it takes another 10 to 20 minutes for that queue to clear after the bridge closes. So a single opening can realistically cost you 20 to 40 minutes if you arrive right as it starts.
So locals do not plan around "the bridge opens at 4:00." We avoid that road from about 3:50 to 4:40.
Why this matters for your day
Three groups feel this the most:
- Cruise passengers heading back to the port. If your ship is docked in Philipsburg and you spent the day at Maho, Mullet Bay, or a Simpson Bay beach club, you have to cross this bridge to get back. An all-aboard time of 4:30 PM and a 4:00 PM bridge opening is a stressful combination if you leave the beach at the last minute.
- Airport transfers. The airport sits on the Maho and Simpson Bay side of the bridge. If you are coming from Philipsburg, Dawn Beach, or the French side and you hit an opening, a 20 minute drive can become 50. For a flight, that margin can be the difference between making it and not.
- Anyone touring both ends of the island. A day that includes Orient Bay or Grand Case in the morning and Maho in the afternoon crosses the corridor twice. Time the crossings between openings.
How to beat the bridge traffic
- Plan your crossings between openings. Look at the schedule and aim to be through Simpson Bay well before an opening, or comfortably after the queue clears. The mid-morning gap between 11:30 AM and 2:00 PM is the longest window of the day, which makes it the easiest time to cross.
- Build a buffer for anything with a deadline. For a flight or an all-aboard time, add 30 to 45 minutes on top of your normal drive time if it lands anywhere near an opening.
- Know the Causeway Bridge as a backup. The Causeway is a separate crossing over the lagoon with its own, lighter schedule (see below). It can save you when the Simpson Bay Bridge is open, but it also opens on its own times, so it is not a guaranteed detour. Check both before you count on it.
- Leave the beach earlier than feels necessary. Missed ships in St. Maarten usually come from a bridge opening between the beach and the port. When in doubt, head back one opening early.
- Let a local driver handle the timing. Every airport transfer and shore excursion we run is planned around the day's bridge windows, so you are never the car that arrives at 3:59 PM.
The other bridges: Causeway and Sandy Ground
There are two more bridges worth knowing about.
The Causeway Bridge (Dutch side, free) crosses the lagoon and can serve as an alternate to the Simpson Bay Bridge. Its 2026 schedule is lighter:
| Opening time | Direction |
|---|---|
| 8:00 AM | Inbound and outbound |
| 10:00 AM | Inbound and outbound |
| 4:30 PM | Inbound and outbound |
The Sandy Ground Bridge (French side, in Marigot, free) matters if your day runs through the French capital. It opens twice:
| Opening time | Direction |
|---|---|
| 8:30 AM | Inbound and outbound |
| 5:00 PM | Inbound and outbound |
Frequently asked questions
How long is the Simpson Bay Bridge open each time? Usually 10 to 20 minutes, depending on boat traffic. Add another 10 to 20 minutes for the car queue to clear afterward, so plan for 20 to 40 minutes of disruption around each opening.
Does the bridge open on weekends and holidays? Yes, it generally runs the same daily schedule, though times can be adjusted for holidays, weather, or special events. Confirm the current schedule with the port authority or your driver if your timing is tight.
Can I walk across when the bridge is open? No. When the bridge is open for boats, it is fully open, and no pedestrians or vehicles cross until it closes again.
What is the difference between the Simpson Bay Bridge and the Causeway? Both cross the Simpson Bay Lagoon on the Dutch side, but they are different bridges on different roads with different schedules. The Simpson Bay Bridge is the main coastal route through Simpson Bay village; the Causeway is a separate span that can act as a backup.
Which side backs up the worst? It varies with the time of day, but the afternoon openings tend to cause the heaviest queues through Maho and Cole Bay, which is exactly when cruise passengers are trying to get back to Philipsburg.
Don't let a bridge cost you your flight or your ship
The Simpson Bay Bridge is not complicated once you know the schedule, but it catches a lot of visitors off guard. The fix is simple: know the seven daily openings, cross in the gaps, and never cut it close when you have a deadline.
If you would rather not think about any of it, that is what we are for. Our private airport transfers and shore excursions are timed around the bridge every day, so your driver already knows whether to leave five minutes early or wait out an opening.
Bridge times are published by the St. Maarten port authorities and were current as of mid-2026. Schedules change, so verify close to your travel date.
