Converting Road Outline (Polyline) to Polygon

I have got our road network outlines drawn with a Polyline feature class, made up of several thousand features. They are shown as the thin black line on the attached drawing.


I would like to convert this feature class into a (single??) polygon type, the area I would expect to be correct is highlighted pink in the attached screenshot.

I have tried using the construct polygons tool on the road outline polyline feature class, which has created the blue features in the below screenshot.


In the sample area, you can see there is a single feature that actually looks correct, all the rest it has constructed on the 'wrong side' of the polyline, so I think there must be a better way to do what I am trying to do. 


Any pointers to get me started?
