Description:
This coverage contains arcs representing the major primary and secondary highways in the state of Iowa. The data was originally obtained from the Iowa Dept. of Transportation. The IDOT data was missing road numbers and arcs running through urban areas. Missing arcs, road number designations and a road type code were added. The type code can be used to make a display that looks like the state highway map.
