Palomino to Santa Marta airport: the 4,20-metre military bridge you cross, and why the airport is on the far side of the city

Two things decide this transfer, and neither of them is distance. The first is that the bridge at kilometre 37 collapsed in February 2026 and what you cross today is a 64-metre military bridge 4,20 metres wide, with the permanent replacement estimated at up to two years away. The second is that Santa Marta's airport is on the opposite side of the city from Palomino, so you do not drive to Santa Marta, you drive through it and out the other side. This page gives you both, from the authorities that published them, plus the Tayrona closure dates that catch people out on the same road.

The bridge at kilometre 37

This is the most important thing on the page, and almost nobody selling transfers on this coast mentions it.

On 3 February 2026, INVÍAS published a notice of total closure of the Santa Marta – Río Palomino road. The bridge over the río Mendihuaca, at kilometre 37, had collapsed. The cause INVÍAS gave was una creciente súbita del río Mendihuaca — a flash flood — which struck the central pier and did serious damage to the structural elements and the deck.

The effect was not a delay. It disconnected Magdalena from La Guajira on this corridor entirely. The official alternate route INVÍAS published ran Bosconia – Valledupar – Cuestecitas – La Florida – Riohacha — which is to say, inland and around, a completely different journey.

On 31 March 2026 INVÍAS opened a military bridge at the site, built by the Ingenieros Militares del Ejército Nacional with support from the Gobernación del Magdalena. Its published specification is precise: el puente de 64 metros de longitud y 4,20 metros de ancho soporta 52 toneladas. The structure arrived on 9 March and was in service twelve days later.

The minister, Mafe Rojas, was explicit that this is not the end state: esta obra le devuelve la conexión a las comunidades... Estamos trabajando para que esta sea una solución de transición hacia una infraestructura definitiva.

On the permanent replacement, the INVÍAS director general Juan Guillermo Jiménez Gómez was quoted on 1 April 2026 saying the new bridge could take up to two years: around nine months of studies and design, followed by an 18-month construction phase. We flag that as a statement carried in the press and not a published INVÍAS programme document.

What 4,20 metres means

Take the one number that matters and think about it for a second.

A standard highway lane in Colombia is around 3,5 metres. A deck 4,20 metres wide therefore carries one lane of traffic, not two. Everything using this national trunk road — cars, buses, the freight moving between Magdalena and La Guajira — crosses in one direction at a time.

That is why we will not give you a journey time for this route, and why we build margin into it instead of quoting tight. The distance has not changed since 2025. The crossing has.

The 52-tonne rating is the other half of the picture: it is enough for normal traffic, which is why the corridor functions at all, but it is a temporary military structure doing the work of a highway bridge on an indefinite timescale.

The airport is on the far side of the city

Here is the mistake people make planning this transfer, and it costs them a flight and not a few minutes.

Palomino is east of Santa Marta, along the coast towards La Guajira. Santa Marta's airport, Simón Bolívar (SMR), is south of the city, on the side facing Ciénaga. The two are on opposite sides of Santa Marta.

So “Palomino to Santa Marta airport” is not the coast road plus a short hop. It is the coast road, plus crossing or skirting the entire city, and then continuing out the other side. The city section is urban traffic on an arrival day at a Caribbean port town, and it behaves accordingly.

People who book this transfer as though the airport were the near edge of Santa Marta are the ones who arrive at the desk as it closes. The city is not a formality on this route; it is a leg.

You drive past Tayrona, and it closes

The road from Palomino to Santa Marta runs along the edge of Parque Nacional Natural Tayrona, and passes its entrances. Two things are worth knowing even if you are only driving by.

The park closes three times a year. These are not maintenance shutdowns; they are periods requested by the indigenous peoples of the Sierra Nevada for spiritual work, and Parques Nacionales publishes them:

• 1 to 15 February — Kugkui shikasa
• 1 to 15 June — Saka Juso
• 19 October to 2 November — Nabbatashi

The October window is the one that catches travellers, because it lands in a period people assume is high season. The road stays open throughout; it is the park that shuts.

If you are stopping, the gates have hours and they are not the same. Parques Nacionales publishes Calabazo at 6:00 to 13:00 all year, and Zaino at 8:00 to 17:00 in low season and 7:00 to 15:00 in high season. The published entry rate for a foreign non-resident is $81.000 in low season and $96.500 in high season.

The practical consequence for an airport transfer: a Tayrona stop on the way to a flight only works for an early departure from Palomino and a late flight, and it needs to be agreed before the day, not at the gate.

What the Troncal del Caribe is like

This is a coast road through a national park and a string of small settlements, not a highway. It is two lanes for effectively its whole length, it carries the freight between two departments, and it has villages on it where the speed limit exists for a reason.

The scenery is good — the Sierra Nevada on one side, the Caribbean on the other — which is part of the problem, because it is also a road where people overtake on a blind rise to get a view.

Add the single-lane crossing at kilometre 37 and the shape of the journey becomes clear: the average speed is set by a handful of specific points, not by the whole route. That is a road where an early start buys you more than anything else you can do.

How we time this against a flight

Three things about how we run this one, stated as choices, not facts.

We work backwards from the check-in desk, not from the distance. The inputs are the flight, the state of the crossing at kilometre 37, and the city traffic on the day. The distance is the least informative of the three.

We start earlier than the map suggests. On a route with one single-lane bottleneck and no parallel road, the cost of leaving early is a coffee at the airport and the cost of leaving late is the flight.

We check the bridge before we confirm. A temporary structure on an indefinite timescale is not something to assume from a page written weeks ago.

If your flight is an early morning departure, say so when you book. On this route that changes the plan materially, and for some itineraries the plain answer is a night closer to the airport, not a very early run along the coast.

How long it takes

No Colombian authority publishes a door-to-door journey time for Palomino to Santa Marta airport, and on a corridor whose throughput is set by a 4,20-metre bridge we are certainly not going to invent one.

What is published and useful: the crossing sits at kilometre 37 of the Santa Marta – Palomino road, so it falls on the Santa Marta side of the middle. The section beyond it, through the city and out to the airport, is the part that varies with the hour and not the road.

We quote this route by departure time, not duration. It is the only fair way to price a road with a single-lane bridge on it.

Common questions

Is the road from Palomino to Santa Marta open?

Yes. It was closed completely after the Mendihuaca bridge at kilometre 37 collapsed, with INVÍAS publishing the closure on 3 February 2026, and reopened when INVÍAS put a military bridge into service on 31 March 2026. Because a temporary structure can change status, we check the crossing before confirming a transfer.

What is the bridge like?

It is a military bridge built by the Ingenieros Militares del Ejército Nacional: 64 metres long, 4,20 metres wide, rated to 52 tonnes. At 4,20 metres it carries one lane, so traffic crosses in one direction at a time.

When will the permanent bridge be built?

The INVÍAS director general was quoted on 1 April 2026 saying it could take up to two years: about nine months of studies and design, then an 18-month build. We flag that as a statement carried in the press instead of a published programme document.

Why does this take longer than the distance suggests?

Two reasons. The single-lane crossing at kilometre 37, and the fact that Santa Marta's airport is south of the city while Palomino is east of it, so you cross the whole city to reach the airport.

Can we stop at Tayrona on the way to the airport?

Only with an early start and a late flight, and only if it is agreed in advance. Parques Nacionales publishes the Calabazo gate at 6:00 to 13:00 all year and Zaino at 8:00 to 17:00 in low season or 7:00 to 15:00 in high season, so the park window and the flight window have to be made to fit before the day.

Is Tayrona ever closed?

Yes, three times a year, at the request of the indigenous peoples of the Sierra Nevada: 1 to 15 February, 1 to 15 June, and 19 October to 2 November. The road stays open; the park does not.

What does Tayrona cost to enter?

Parques Nacionales publishes $81.000 for a foreign non-resident in low season and $96.500 in high season.

What are the tolls on this route?

There is a toll plaza at Neguanje on this corridor. We could not obtain a current published rate table from the concession, so we do not quote a figure. On routes where the operator publishes its table, we reproduce it in full.

Should we leave the night before for an early flight?

For some itineraries, yes, and we will tell you so. On a road with one single-lane bottleneck, a very early departure from Palomino for a dawn flight carries more risk than it needs to.
