Pylons
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.

If there is a larger takeaway here perhaps it is about paths of least resistance, with regards to both the actual flow of water and design decisions. On the one hand, it is easy to blindly follow regional precedents and traditions with long histories (or grab whatever is handy at the hardware store). On the other hand, sometimes it makes sense to take a step back and decide consciously how to reveal (or conceal) a natural process.
