Assuming you will connect to I-64 west from the CBBT, VA Beach, Norfolk, Hampton, Newport News and York/JCC/Williamsburg each have trunking systems which the 96 can monitor. You will also be passing nearby Norfolk NavBase and Langley AFB - both with digital 400 Motorola trunking systems. NavWeps Station and Ft Eustis are both ajacent to your route but conventional.
There are also several LTR business systems near your route including Williamsburg so you may want to bring the 97 also.
I have various p96 files which can easily be set for your route on this side of the Chesapeake Bay.
Also, one source for data is under my signature.
