Additional notes

• The rendering of residential construction roads seems to use the same total width (including the casing) as the rendering of residential roads. Nevertheless, the visual impression is that the construction residential road is wider than the residential road.
• The construction rendering uses the z13 casing width for z14. That seems a little wired, not sure if it’s intentional or a bug?

Yes, it seems too heavy, it might be a good idea to (a) move to basing the dashing color of construction roads on the landuse=construction color and (b) lighten the color to use for white roads so the contrast is similar to that of other road types.

If someone wahts to work on construction roads rendering - we also have two other long standing issues about that: #398 and #761.
