Driving Through the Felbertauern Tunnel in the Heart of the Alps

# Felbertauern Tunnel: Austria's Alpine Gateway

Tucked away at 1,650 meters (5,413 feet) in the heart of Austria's Hohe Tauern National Park, the Felbertauern Tunnel sits right on the border between Salzburg and Tyrol. Before this marvel was completed in 1967, getting from East Tyrol to Innsbruck meant taking a serious detour—either through South Tyrol or tackling the seasonal Großglockner High Alpine Road. Not ideal, especially when winter hit.

Named after the nearby Felbertauern Pass (which peaks at a beefy 2,481 meters), this impressive tunnel stretches about 5.3 kilometers (3.3 miles) and ranks among Austria's longest road tunnels. It's a single-tube setup with two-way traffic, and yes, there's a toll to use it.

The whole experience is surprisingly modern for an Alpine crossing. The road (B 108) is fully paved, with more than a third running through protective avalanche galleries and tunnels—because this is serious mountain terrain. Over half the route actually features three lanes, and you'll find long stretches spanning elegant bridges. The gradient never exceeds 10%, though the approach ramps can hit 9.3% in steeper sections.

Running north-south from Mittersill in Salzburg to the medieval town of Lienz in Tyrol, the 65-kilometer (40-mile) route climbs through some dramatic Alpine scenery. The best part? It's open year-round, so you're not stuck waiting for summer to cross. Just pull up to one of the tunnel portals and arrange a shuttle if you prefer—easy as that.
