Hi, Having set out many roads during my early days as an engineer, the width are as follows, main trunk road two lanes 10ft wide, secondary road lanes 9ft wide, estate roads lanes 8ft wide. thats since the war. Before that most roads were either 16ft or 18ft wide between faces of kerbs in residential areas, country areas could be anything from an 8ft track with 2 strips of hard surfacing to a full 16ft wide tarmacadum surfaced road.
There were others but the above is the most likely sizes you would have found, for your model just multiply the ft size by 4 and thats the width in millimetres, simple!
