Some data not displaying

Another question.

I have a map project that I am working on for class and unfortunately not all of my information is showing up (file included). The red highway lines should all connect with one another.

All the datasets were provided by the textbook so I assume they are right, though you should never assume anything. I have set the Current Workspace and Scratch Workspaces as others have reported this to help them work out their display problems.

Any help would be greatly appreciated.

Mapping Center Answer:

It looks to me like you are symbolizing the roads layer you are talking about using Categories > Unique Values (on the Symbology tab of the properties for the roads layer).  If that is the case, then you are using an attribute to assign the symbol to each road segment.  Double check the roads that should be red and make sure they all have the same attribute value.  If they do not, then that is your problem. There might be a different attribute you can use instead that DOES have the attributes and values to assure that the roads that should be shown the same have the same values.  Or you may have to edit the data to change the attribute values in the road class, or to add a new attribute and select the roads that belong in the same class and give them the same attribute value.
