The problem is that if you simply scale it, you get a mess:

So, there are two ways to fix it.
!! Script Way
One solution is to use the "Inset Outline" script from here: [http://panoptic.com/rking/blender/inset_outline.py] with a negative value to make it Outset instead of Inset.
!! Manual Way
Another solution involves scaling along some normals, using a temporary Solidify modification and then Alt+s.
1. Duplicate the road (Alt+d)
2. Add a Solidify modifier:
2. Solidify the shape by extruding it downwards.

3. Make it thick enough that you can see the sides, say .5, then hit Apply:
3. In Face Select mode (Alt+Tab, F), and Alt+RMB to select the sides:

6. Select the extra chain of faces with Alt+RMB, and delete them, too.

7. Make sure both roads have their origins in the middle, by Ctrl+Shift+Alt+C > Origin to Geometry

8. Hit 'n' to bring up the Properties panel, and Copy the Z value from the skinny road (Hover over the value and hit Ctrl+C):

9. Paste it onto the Z value of the fat road:
