Hello qsiguy,
use the eye-symbol and click on the bus. The information should be at least: A[0..15],D[0..7].
If you don't get it that circuit is not engineered. It's just a simple drawing and nobody except for the author knows which net has to go from where to where.
Bus intersections should be marked as such. One could assume it is just one bus, but I guess there are two different buses, one for the addresses and the other one for the data. Further it's always a good idea to label the buses.
