This thread I dedicate to my favourite Lviv's paving, a great basalt paving which was in the majority of the streets in Lviv's centre till 2006. Since that year Andriy Sadovyy became a mayor of the city and he is Lviv's mayor till nowadays. In common there was and is a problem of the bad roads in Ukraine and Lviv isn't an exception in it. Yes, Lviv needs good roads in the streets. But the views of the decision of this problems were and are very "interesting" in Lviv's mayor. Instead of new roads' construction in the city he decided to re-construct the roads in the historical part of Lviv and almost all central streets, including centralest street Svoboda Avenue, which were paved with basalt paving earlier.
I must say You that tradition to cover streets with nice paving has yet begun since 1462 in Lviv. So Lviv's historian Denys Zubrytskyy in his "Chronicle of the city of Lviv" ("Хроніка міста Львова") wrote that in that 1462 year was constantly lasting a process of the paving of new streets. Because Lviv was one of the main cities in the Polish kingdom. But the biggest quantity of Lviv's central streets was paved since 1772, when Lviv became a territory of Austro-Hungarian Empire. And almost all roads' paving in the centre was made with black basalt, which is considered as a strong stone and as an expensive building material for roads. That basalt paving was laid out in semicircle's form and looked very amaizing. Till 2006 Lviv's paving of XVIII-XIX centuries was more than in Cracow and in many European cities, probably only Vienna and Prague had and have nowadays more ancient basalt paving than Lviv. It's a very pity, but a few Lviv' streets have such wonderful paving now. One of them is Halytska street, its photo You can see below (basalt paving after Lviv's rain on January 14th, 2011)

And since 2006 reconstruction was becoming in Lviv's central streets and some of them got a new paving from shareless stones or were asphalted. There wasn't a necessity in that reconstruction, because these more tnan 200-year-old basalt pavings were in the perfect state. And the streets got much worse appearance after that reconstruction. Here You can see the road of Rynok Square, historical centre of Lviv!, after such "reconstuction" (photo was taken myself after rain last week)

And after all the main questions are WHY mayor A. Sadovyy did roads' "reconstruction" and WHERE this perfect basalt pavings from many Lviv's streets went.

I can't believe that such "activity" was held in my native town. For what? Can You believe that the street on the next photo is a road before famous architectural monument "Chorna kam'yanytsa" ("Black building") on Rynok Square in Lviv? But that's true, here it is (photo of January 14th, 2011). And before "reconstruction" there was nice paving from basalt, such as You can see on the photo n. 1.

So in such way are good roads built in the world? I don't think so.
