How fast can they go? And how do they even have space roads, since everything in space is moving relative to everything else?

Energy bridges. Also, the bridges I saw went from the ground to cities built in space, not far from the far reaches of the gravitational field. The positions of the cities remained the same relative alto the planet as the planet moved because of the way they designed it. Man, I am boring myself.
