Bregenz to Silkeborg Road Trip: Alpine Fjords to Danish Lakes

This 1075-kilometer road trip from Bregenz to Silkeborg crosses four countries—Austria, Germany, and Denmark—following the A1 and E45 highways.

A specific fact: the stretch between Flensburg and Kolding uses the E45, which was originally built as a military road during the Cold War, explaining its unusually long straight sections.
