This is a picture I took a year ago in Espoo, Finland. What I liked here was the sign vessel of the road sign with yellow background. We can see with a glance that this is a temporary as it is not of the same standard form as the official road sign "Sierakiventie - Brynstensvägen" next to it. But it is also not something that has been put up on a whim. The base is a concrete road works block weighing hundreds of kilograms, meaning that heavy machinery was most likely used to install this sign. This both lends it some special credence, and hints that whatever the cause of this alteration of routing is, it will not be permanent but not a short event either.
