How to drive the Single Lane Tunnels/Bridges of Iceland?

Cruising through Iceland, you'll find some quirky one-lane tunnels and bridges, especially off the beaten path! Don't sweat it; just remember the golden rule: yield to oncoming traffic.

These tunnels have frequent passing spots, like little pull-offs every 100-150 meters. If there's a passing spot on your right, that's your cue to pull over and let the other vehicle roll on by. Signage or lights at the entrance will often give you the heads-up on who has the right of way.

These tunnels are cozy, so speed limits are strictly enforced. Take it slow, turn on your headlights, and be ready to yield. Standard-sized vehicles usually cruise through just fine, but larger trucks or buses might find it a bit snug. Some rental car companies even suggest avoiding certain ones, especially when winter hits.

The Dalvík to Ólafsfjörður Tunnel in northern Iceland is a 3.4-kilometer (2.11-mile) single-lane adventure with plenty of passing points. Built in 1990, it's a safe shortcut through some seriously mountainous terrain.

Near Siglufjörður in North Iceland, there's an 800-meter (0.5-mile) tunnel built back in 1967. It's a classic single-lane setup, so keep your eyes peeled for oncoming traffic and make good use of those passing areas!

Then there's Iceland's first tunnel in the Westfjords. It's a tiny 30-meter (98-foot) wonder. Though technically two lanes, it's pretty narrow. Connecting Ísafjörður and Súðavík, it's like a quirky historical landmark from 1948.

As for one-lane bridges, the closest car gets the right of way, then it's an alternating turn system for everyone else.
