Descriptions:
This mod greatly increases traffic density in major urban areas across the map; traffic elsewhere is kept to vanilla levels, which I think is realistic enough. It also widens freeways and urbanizes some areas that are particularly inaccurate in the original map. Use the available “Lite” version if you want only the scenery/signage changes in California and Phoenix Area.

Update 15 November:
Small fixes to SCS signage errors in the Phoenix area.
Very high traffic area in San Francisco’s Embarcadero downgraded to just a high traffic area.
Small scenery fixes in Reno and Barstow.

Very high traffic areas added:
Boise (I-84)
El Paso
DFW – San Antonio Corridor
Houston Area

Map in the OP was finally updated also.
