The Norwegian Fv946 is one of the steepest roads in the world

# Fv946 (Tronåsen): Norway's Gnarliest Mountain Drive

If you're craving an adrenaline-pumping road trip, buckle up—Norway's Fv946 might just be your ultimate challenge. Nestled between Rogaland and Vest-Agder counties in southern Norway, this legendary route sits at the northern tip of Lake Lundevatnet and will test even the most confident drivers.

We're talking about one of the steepest roads on the planet here. With gradients hitting 25-33%, this isn't your average Sunday cruise. The road demands respect—weak engines and dodgy brakes have no business here. Seriously, some cars actually need to reverse up sections because forward gears just don't cut it. That's the kind of intense you're signing up for.

The numbers alone tell the story: just 5.4 km (3.35 miles) of pure, concentrated mayhem. Starting from a parking area along E39 (complete with facilities), it climbs to Bakke Bro, a stunning 1844 suspension bridge spanning the River Sira. The route is narrow—only 2.5 to 3.5 meters wide—and twists through 11 wickedly sharp hairpin turns. The pavement exists, sure, but it's seen better days.

Here's the history kicker: this road has been connecting travelers since 1791 and was officially paved in 1844 as part of the Western Highway. It was originally built for horse transport (imagine that!) and was such a proving ground it earned a spot in the 1931 Rally Monte Carlo.

Fair warning: it's only open to regular cars May through September. Large vehicles, caravans, and trailers? Not happening—ever.
