You probably want to look at the attributes the identify road class and 
you can either:

1. order the data by road class
2. split the data into different files based on road class
3. just filter the data for the road class you want

Then draw the LAYERs in this order:

ramps
trails
minor roads
secondary roads
major roads
highways
interstates

And this should give you a similar layering.
