I want to improve/update the lane information on the US highways where I traveled (maybe I’ll come back there one day and use OSM for navigation). The first one is US 6 in Utah, a part of the route between Salt Lake City and Moab, where great Arches and Canyonlands National Parks are. Bing aerial imagery is pretty good and recent in the US, so it’s pleasant to use. It’ll be an ongoing project in between other mapping.

What I’m mapping:

• number of lanes, turn lanes, change lanes (near intersections), placement;
• removing note:lanes where it’s now redundant;
• turn restrictions including implicit ones;
• connectivity relations inferred from road markings;
• occasionally aligning the road to the Bing aerial photos.
