As reported on the site of government purchases today, with two contracts for 401.4m and 573.4m rubles, contractors have to lay 343 km of borders, of which 171 km must be done within 25 days. For example, the carriageway of sidewalks in the center of Moscow will need 11 km of red board stones to separate the carriageway from grass, 8.5 km of which is to be a grey border. It will also be necessary to lay light grey curved borders. All of this will be made from the granite extracted from three Russian mines: "The Flower of the Urals" in the Chelyabinsk region, the Mansurovsky deposit in Bashkiria and from the red Sultayevsky granite also from the Chelyabinsk region.We remind you that the Vice-Mayor of Moscow for housing and communal services, Pyotr Biryukov, promised to change all stone borders in the capital in three years. It is about repairing broken barriers and not about reconstructing the existing ones.
