If the entire road width is 64x, then you can use my design fr the roads, dunno if it fits the style though.
I'll try and explain it.
Bricks needed:
16x16 print baseplate
2x1 print plate
2x2 print plate
Place two yellow lines of the 2x1 print plate down the center, forming a doubled yellow line, use prints to create a gapped look inbetween the lines, then, place four 16x16 print baseplate on each side of the center line. And you are done. There should be a 14x wide area on each side that can be used for side walks.
