How long it would take to cross the world’s longest highway that starts in the USA and spans 30,000 km across 14 countries

The longest highway in the world spans through 14 countries and is the ultimate road trip for any fanatics. But how long would it take to cross the 30,000km road network?

It’s a big, wide world, and there’s much more to discover than the deep dent in our office chairs.

But carving out the time to see everything that Earth has to offer not only takes a lot of time, but a lot of planning.

Thankfully, one network of roads called the Pan-American highway connects 14 countries in a 30,000km trip.

The longest highway in the world connects Canada and USA to Southern Argentina

While the US boasts some magnificent highways that are perfect for road trips, such as Route 66, the ultimate journey in the Western Hemisphere spans from Prudhoe Bay, Alaska, to Ushuaia, Argentina.

Starting in Canada, the Pan-American highway runs through the USA, Mexico, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, and Panama, before crossing the ‘Darien Gap’ to Colombia, Ecuador, Peru, Chile, and finishing in Argentina.

Technically, the longest highway is more of a network of roads, with no single stretch or tarmac going from one end to the other, as no road passes through the Darien Gap in Panama.

This remote area is a circuit of swamps, marshes, and dense rainforest, is renowned for its thick wildlife and dangerous diseases, which make it impossible to cross.

Instead, the border from Panama to Colombia is crossed by a ferry, which theoretically connects the longest highway in the world.

But it’s widely regarded as one of the best (and longest) road trips in the world, taking you through so many countries and cultures.

So, how long does it take?

How long does it take to cross the Pan-American highway?

Well, by car, this could technically take anywhere between 12 days to a couple of months, depending on your pace.

While not a regular occurrence, it’s technically possible to take shifts, driving constantly (taking shifts like truckers do) at an average pace of 60mph and complete the path in 300 hours (12.5 days).

But more feasibly, if you kept up that pace for eight hours a day, it would take 900 hours (37.5 days) to complete.

Then, if you’re brave enough to try and walk it (believe us, people would try), then it would take years, even at the most aggressive of paces.

However, even some of the best cars in the world have fallen to the perilous Pan-American highway.

Still, for anyone with a spare five and a half years and a good pair of walking boots, it could offer some nice views.
