Westpark tollway Bluetooth "dead zone"

Every time I take Westpark tollway Westbound from the 59 exit my wireless android auto resets at the same spot, a little past Fondren. It doesn't happen when I'm traveling eastbound back into downtown. At first I thought it was a time thing since I am usually at the same spot at the same time, but now that my schedule is not as regular I'm realizing it is in just that spot.

Does this happen to anyone else? Any idea what is going on?
