Hi Jonathan,

Yes, there is absolutely a way to do that, but it is going to take a bit more work than some of the other properties where you can just check a box and be done with it.

What you will have to do here is use the interstate highways as a "line barrier" in your network dataset. That way, when you generate your closest facilities layer, it will not accept routes that include highways as an acceptable option.

As this knowledge base article points out, there are two ways to effectively create a line barrier: manually using snapping, or utilizing a streets layer. How to do each one is outlined in the article. Here is a link to the documentation on Network Analyst barriers, in case you aren't familiar.

If you don't have your own streets layer, ArcGIS Online has one available that includes all streets in the US. You can then select by the streets classification and create your own highway layer to use for this.

Please let me know if you have any questions, and good luck!
