I googled sump-pit and now I understand their use in a trench, but how can a sump-pit be used in or on a road?

Erik, I'm not an engineer, but I would assume in this case the sump pits collected water runoff to ensure that the road surface stayed well drained and usable. Think of it as a form of drain.
