That doesn't look too bad. If they just cut in the pavement and not the road. They will have to shift a lot of cars from the pavements around here first though.
They'll have to cross roads somewhat too, obviously, but where possible will use the pavement. It costs a fair bit more to go through the carriageway.
Regarding placement of pots / Toby boxes: they will go as close to your property as possible while still being on public land. If you're on a private road or have private driveway they'll build the Toby at your property boundary or the road boundary unless you have agreed and signed a wayleave agreement, however that is at the discretion of whomever is managing the project.
