Tallest poles ever
Along my route N20 and N22 from France to the highest pass in the Pyrenees located in Andorra (see my off the beaten path tip) I saw numerous poles put along the highway to mark the road edges while covered by snow. These poles where the tallest I ever saw, probably about 4 m tall at the pass. In May snow was removed from the road and luckily that day I drove there there was no fog but beautiful sunny weather.
The very scenic mountainous road from France to Andorra is well maintained and open all year round. Rarely it's closed due to heavy snowfall. That time you have to drive through the toll tunnel in France, first to Spain and reach Andorra from the South.
Most folks think that the highest paved road in Europe is located in the Alps. In real it's in Spain, not in the Pyrenees though. It's in the Sierra Nevada Mountains in the southern Spanish province of Andalousia: Pico Veleta (3,398 m; 11,150 ft).
