as of 07.07.2013 the mod seems broken
I have installed universal street 2.0 and tried 1.9:
1_Universalstreet_Menu.package into C:\Program Files (x86)\Origin Games\SimCity\SimCityData
base\1_Universal_Street_Script.package into C:\Program Files (x86)\Origin Games\SimCity\SimCityUserData
Problems I have encountered:
all agents use the new Park Street
the new street is not removale - thus cluttering the map as dead space
For me the description which file in which directory unlocks what and how they interact with each other could be a little bit more detailed.
