how to make roads?

[unmerged(125022)]

Still relitivly new player.

I got a growing empire but theirs a few things that bug me.

Why cant I build roads? Do i lack the teck or the trade resorces to build them. I dont really understand why I cant build a road network to make moveing troops faster.. If anyone could explain why or how to do it please let me know.

Another question would be, what is the point of the teck numbers?

You need to have discovered the certain technology to build roads, and that will happen later in game.
Tech numbers? You mean, tech level? Well, to show how advanced your technology is. When you reach some levels, you will be able to get certain discover events... like roads.
