of lindens, designed by the architect I.E. Stamov by garden masters F. Lyamin and M. Prokopin. The level of the boulevard became higher than the pavement; stepped slopes were added opposite bridges and cross streets. Two years later, the boulevard next to the Kazan Cathedral under construction was liquidated, and in 1819 it was completely abandoned in the middle of the avenue, replacing it with ordinary plantings of trees along the new granite sidewalks of the avenue. Landings were interrupted at the Catherine Canal and cross streets. The entire row planting existed until 1841, when by order of the emperor Nicholas I it was liquidated, all trees were transplanted into Summer Garden. Ordinary plantings were restored in 1897 on the sites in front of the Kazan Cathedral (liquidated two years later in connection with the construction of the square) and Gostiny Dvor. In 1832, the pavement on the avenue was replaced with a paved one butts – with hexagonal wooden blocks. This type of end pavement, invented by engineer V.P. Guryev, was first used here, then became widespread in many cities Europe and America. The side paving provided a soft and quiet ride and existed on Nevsky Prospekt until 1924, when the asphalt was replaced. In 1806, one of the first metal bridges was thrown across the Moika – Police Bridge designed by V. I. Hesse. Before that, the Moika was clad in granite. By 1841, the Anichkov Bridge was rebuilt: it was expanded, four granite towers were removed, a cast-iron lattice and horse groups on the theme of taming a horse by a man, created according to the project of the sculptor Peter Clodt. By the middle of the 19th century, Nevsky Prospekt became one of the most comfortable streets. Poor people gathered at the corner of Nevsky and Vladimirsky Prospekt for hiring daily workers, who christened this place "a lousy stock exchange". With the distance from the Fontanka, the volume and height of the houses decreased. On the first floors, often in semi-dark rooms, there were cheap entertainments such as Puppet Theater or wax rooms. The closer to Znamenskaya Square, the more often you come across wooden houses with large yards and vegetable gardens. And the so-called Staro-Nevsky Prospekt with low wooden houses, fences and vast vacant lots looked completely out of the blue. The construction fever in the second half of the 19th century changed the situation.
