# The Bømlafjord Tunnel Roundabout: Norway's Underground Marvel
Tucked beneath the waters of western Norway, near Eidfjord in Vestland County, sits one of the world's most mind-bending driving experiences—a fully functional roundabout *inside* a subsea tunnel. Yes, you read that right.
This incredible feat of engineering lives within the Bømlafjord Tunnel (Bømlafjordtunnelen), part of the E39 highway. The tunnel connects the islands of Stord and Bømlo to the mainland and holds the distinction of being one of the world's deepest subsea tunnels. Navigating a roundabout while underwater? That's peak Norway right there.
**Getting There**
Simply follow the E39 highway and drive straight into the tunnel—just stick to the speed limits and road signs like you would anywhere else. The tunnel is well-lit and designed for regular highway traffic, so it's a straightforward drive despite its unusual feature.
**What to Know**
There's no entrance fee for the roundabout itself, though tolls may apply on the E39 depending on where you enter and exit. Vehicle type affects pricing, so check before you go.
If you're on a motorbike, you can safely snap a quick photo at the roundabout. Car and larger vehicle drivers should skip the photo stop and keep moving. And pro tip: make sure your vehicle is in good condition before tackling long subsea tunnels.
**The Wow Factor**
Here's the kicker—this isn't even Norway's only underground roundabout. The country boasts around 14 roundabouts tucked inside tunnels, with another nearby one just north across a bridge. It's a quirky testament to Scandinavian engineering creativity and the dramatic demands of fjord-region infrastructure.
For adventurous drivers, this is a genuinely unforgettable stop that perfectly captures the spirit of Norway's wild, ingenious landscape.

moderateCroce di Poverzone
🇮🇹 Italy
Okay, picture this: you're smack-dab in the middle of Valtellina, Italy, ready to tackle the legendary Croce di Poverzone. This ain't your average Sunday drive, folks. We're talking a climb to 1,908 meters (6,256 feet!) above sea level. The last 7 kilometers are where the real adventure begins – gravel and dirt roads that'll test your mettle (and your suspension). The climb averages a solid 10% grade, but be warned: some spots crank up to a leg-burning 18%! Word has it that the Giro d'Italia once chewed up this road to Triangia, so you know it's legit. Heads up, though – Mother Nature calls the shots here. Usually, this route is a no-go from October through June, so plan accordingly. If you time it right, you'll be rewarded with views galore!
extremeThe Science of Tread: Water Evacuation and Grip
🇬🇧 England
Okay, picture this: you're heading out on a UK road trip, ready to carve through those twisty A-roads. The sun might be shining now, but trust me, that can change in minutes! Standing water can appear out of nowhere, turning a pleasant drive into a potential disaster. Now, let's talk tires—your unsung heroes. Those four little patches of rubber are all that’s keeping you connected to the road. And here's the deal: if they're not up to scratch, you're playing a risky game. Legally, you need at least 1.6mm of tread across the central three-quarters of the tire. Skimp on that, and you're looking at a hefty fine – we're talking £2,500 and three points *per tire*! But it's not just about the law. Think about aquaplaning. The less tread you have, the harder it is for your tires to grip. At 1.6mm, your braking distance can increase by a massive 40% in the wet compared to new tires! On those narrow, winding roads, that extra distance could be the difference between a close call and a crash. Plus, if you *do* have an accident with illegal tires, your insurance company might wash their hands of you, leaving you to foot the entire bill. Ouch! So, how do you check your tire health? Grab a 20p coin and stick it in the tread grooves. If you can see the outer band of the coin, it's time for a professional inspection. Even better, invest in a proper tire tread depth gauge for accurate measurements. Don't just aim for "legal." Make sure your tires are in tip-top condition. It's about more than just getting from A to B; it's about staying safe and enjoying the ride!
extremeDriving the old military road to Schlusseljoch in South Tyrol
🇮🇹 Italy
# Schlüsseljoch: A Bucket-List Alpine Challenge Perched at 2,212m (7,257ft) in the stunning Zillertal Alps, Schlüsseljoch is one of those legendary passes that separates the adventurous from the faint-hearted. Known locally as Col della Chiave or Passo della Chiave, this mountain gateway sits right on the border between Italy's South Tyrol and Austria, bridging the Val di Vizze to the west with the Valle Isarco to the east. Here's where it gets interesting: the entire 14.1 km (8.76 miles) route is unpaved. This old military track, built with strategic purposes in mind, isn't your typical smooth mountain pass. We're talking narrow, rough, seriously damaged surfaces with steep sections and teeth-rattling hairpin turns. If you're bringing wheels, you'll absolutely need a high-clearance 4x4—and even then, you might want to reconsider. The drive starts near the village of Borgone on the SP508 Road and finishes at the SS12 near Terme di Brennero. It's slow going, demanding every ounce of your vehicle's (and your) capability. **Fair warning though:** many high mountain tracks in South Tyrol are now off-limits to regular vehicles. Before you pack the car, check local regulations around the Sterzing/Vipiteno area first. If it's closed to cars, don't worry—the Schlüsseljoch has become a legendary (and brutal) playground for mountain bikers and hikers. Also worth knowing: this pass gets buried under snow from late October through June, and there's zero winter maintenance. Winter driving? Not happening.
extremeAn old military road to Lago d'Arpon
🇮🇹 Italy
Okay, adventure junkies, listen up! Lago d'Arpon, straddling the French-Italian border, is calling your name from a lofty 1,830 meters (6,003 feet) above sea level. But fair warning: getting there is not for the faint of heart! We're talking serious 4x4 territory only, folks. This "road" – and I use that term loosely – to Lago dell'Arpone is skinny, gnarly, and forget about it in the winter. Think you've got the skills? This one will test them, along with your courage. If you get wobbly knees looking down, maybe skip this one. Landslides? Yeah, they're a thing. But oh, the views! Seriously, your tires will be singing with joy at the panoramic mountain vistas. Just try not to focus on the hundreds of meters of unprotected drop-offs right next to you. This old military road, carved into the Alps back in the day, is a real piece of history. Get ready for an unforgettable, if slightly terrifying, ride!
