A Department for Transport web page provides the post consultation route as an ESRI shape file. This file is released with an Open Government Licence. I've converted this file to GeoJSON. This GeoJSON is used to generate the multi-coloured line.

A Natural England web page provides ESRI shape files describing nature areas such as Ancient Woodlands and SSSIs. These files are released with an Open Government Licence. I've also converted these files to GeoJSON.
