Not all the towers along a transmission line are identical. Look closely at a tower where the line makes a sharp turn and you will likely find it is wider and beefier than other towers along the route. The added strength and weight are needed to resist the unbalanced pull of the conductors, which might overturn an ordinary tower. These special towers are called deviation or angle towers.
The transmission-line tower everybody knows is an Erector Set latticework of steel girders and diagonal braces. The techniques for designing and building these towers are the same ones used in constructing steel bridge trusses or crane booms. The individual pieces can be made cheaply from rolled steel and then bolted together on the site. This last point is more important than it might seem: transporting a fully assembled tower 100 feet tall is an awkward and expensive business.
“Togetherness” is a fittingly nauseating name for an old ideal in planning theory. This ideal is that if anything is shared among people, much should be shared. “Togetherness,” apparently a spiritual resource of the new suburbs, works destructively in cities. The requirement that much shall be shared drives city people apart.
When an area of a city lacks a sidewalk life, the people of the place must enlarge their private lives if they are to have anything approaching equivalent contact with their neighbors. They must settle for some form of “togetherness,” in which more is shared with one another than in the life of the sidewalks, or else they must settle for lack of contact. Inevitably the outcome is one or the other; it has to be; and either has distressing results.
City residential planning that depends, for contact among neighbors, on personal sharing of this sort, and that cultivates it, often does work well socially, if rather narrowly, for self-selected upper-middle-class people. It solves easy problems for an easy kind of population. So far as I have been able to discover, it fails to work, however, even on its own terms, with any other kind of population.
