Mass upgrade for roads?

[Killer Tamashi]

There's no way in HELL i'll spend hours trying to upgrade all the roads I have, is there something I can do to upgrade a bunch of them at once?

I don't recommend upgrading all your roads, but rather focusing on the ones that the traffic layer shows heavy usage on. Also it can be resource heavy and drain a large amount of steel and carbon, as well as taking up a drone the entire time.

That said, the upgrade system in general could be looked at some more...

[Mindmaker]

Not worth it at that carbon cost. You should only upgrade the couple most used roads.

It's probably more efficient to skipnroads snd go straight for Hyperloops though.

Zoom a bit out, hold SHIFT and draw a selection for the buildings you wish to have upgraded roads. Then simply hit the upgrade roads button on the right side. It will upgrade all roads between the selected buildings.
