I found a couple of online documents that summarize the technical considerations. Another document using 2011 numbers determined that 'undergrounding' is about 5x more expensive, not counting the cost of the specialized termination points and not counting increased maintenance costs.The technology exists, but using it just to jog around an obstruction is very expensive. We can use that money to build transit or to bury wires. I know my preference.
