Our instructions call for four transverse roads. Each of these will be the sole line of communication between one side of the town and the other, for a distance equal to that between Chambers street and Canal street. If we suppose but one crossing of Broadway to be possible in this interval, we shall realize what these transverse roads are destined to become. Inevitably they will be crowded thoroughfares, having nothing in common with the park proper, but every thing at variance with those agreeable sentiments which we should wish the park to inspire. It will not be possible to enforce the ordinary police regulations of public parks upon them. They must be constantly open to all the legitimate traffic of the city, to coal carts and butchers’ carts, dust carts and dung carts; engine companies will use them, those on one side the park rushing their machines across it with frantic zeal at every alarm from the other; ladies and invalids will need special police escort for crossing them, as they do in lower Broadway: eight times in a single circuit of the park will they oblige a pleasure drive or stroll to encounter a turbid stream of coarse traffic, constantly moving at right angles to the line of the park movement. The transverse roads will also have to be kept open, while the park proper will be useless for any good purpose, after dusk, for experience has shown that even in London, with its admirable police arrangements, the public cannot be secured safe transit through large open spaces of ground after nightfall. [Sidenote: Foreign examples.] These public thoroughfares will then require to be well lighted at the sides and, to restrain marauders pursued by the police from escaping into the obscurity of the park, strong fences or walls, six or eight feet high, will be necessary. A public road thus guarded passes through the Regent’s Park of London, at the Zoological Gardens. It has the objection that the fence, with its necessary gates at every crossing of the park drives, roads or paths, is not only a great inconvenience but a disagreeable object in the landscape. To avoid a similar disfigurement an important passage across the garden of the Tuileries is closed by gates at night, forcing all who would otherwise use it to go a long distance to the right or left.
