ATC has declared that building this line underground is not possible. From their website: "For higher voltage transmission lines such as the 345-kilovolt line being proposed for the Rockdale to West Middleton project, undergrounding is not a viable option because at that voltage the lines cannot dissipate heat and become capacity bottlenecks on the system, defeating the purpose of building them."
The technology to bury the line exists, and it has been done for years all over the world. It is also being done right here in the United States. The City of San Diego, California has decided to underground new powerlines; all new projects will be underground, and by the year 2020, all existing overhead lines will be buried.
