At first this looks plain stupid.
However, one would hope there was actually careful planing in building the new road AND in moving the pylons but that they were just not executed in the right order… and it was probably better for the road contractor de build the road anyways, letting the electric people deal with removing the pylon later and leaving only – maybe – a small pothole in the road… And fixing the “pothole” later is only a small job/problem compared to building the whole road later.
