Carto stylesheets used in Tilemill; deriving from migurski's high-roads and his views.psql, this stylesheet allows bridges and overpasses to neatly display. This stylesheet requires your data (at least the roads portion) to be in a postgis database, imported from osm via osm2pgsql.
higher-roads's Introduction
The readme file.
This is an exercise to become familiar with migurski's high-roads.
What's unique to this, compared to his high-roads, is that I intend to have more than just '3' levels, in fact, I plan to have about 7 or so, based on Openstreetmap's taxonomy
[in the USA], so there'll be:
motorway
Primary
secondary
tertiary
residential/unclassified
service
Right now, this is in its infancy stages and still only has support for 3 levels: Highways, major roads, and minor roads
