The Reconstruction of Moscow

The major elements in the width of a city street are as follows: a sidewalk with a minimum width: of' 3 metres on each side- of the road, a street- car line with a minimum width of 7 metres, and a roadway oh either side of the street- car line with a minimum width of 3.5 metres- on either side. Thus, the narrowest street with a street-car line and a roadway designed for a single column of ve- hicular traffic in both directions should be 20 metres. But since streets with street-car lines cannot as a rule be limited to a single column of vehicular traffic and the minimum width for the sidewalks, it is estimated that the отшшшт width for Moscow streets should be the following: sidewalk-^4 to 5 metres on either side, the roadway— accommodating 3 columns of vehicular traffic (a column in either direction arid one side for parking) -—8 to 9 metres on either side, and the street-car line— 7 to 9 metres, making a total of approximately 30 to 35 metres (sidewalks 8 to 10 metres, roadway 16 to 18 metres, stre,et-car lines 7 to 9 metres). The busy streets and main thoroughfares, however, will have sidewalks approximately 6 metres wide, and in many cases will be lined with trees, which in their turn will take up not less than 2 metres. The roadways will be designed not for a minimum average of 3 columns of vehicular traffic, but for at least 4 to 5 columns which will take up no less than 15 metres of roadway on either side. In those, cases where the street-car lines are left on such streets, the total width will be 53 to 55 metres (side- walks^ — 12 metres, planted area-^l metres, roadway— 30 metres, street- car lines— 7 to 9 metres). A number of the principal thoroughfares will be 60 to 70 metres wide. In such cases the sidewalks and road- ways will not be made wider, since the widening of the roadway to allow for 5 columns of vehicular traffic would
