Closing lines and faces

A street map covering a lot of area won’t close the loop for the faces in the streets to show up. Instead have to draw in multiple lines at intervals until the entire loop/streets contains faces, which is time-consuming. All the lines were already closed with “Weld Edges” tool and set to co-planer with “Align endpoints” tool. Is there another menu item that connects on the lines to close the loop saving time?

You can try Eneroth Face Creatot, but the roads don’t seem to perform perfectly even with that.

Thanks, I have used other tools Sketchup through trial and error. And sometimes works. I’ll keep working with it, thanks
