This is a similar problem to what I described on the NB service plaza side. In this case, access to the I-95 SB service area for EV charging is available but the mapping software does not describe the two-way status of the SB exit ramp starting at this point. There is a very small access road showing that enters into the SB service plaza that allows entering and exiting from the service plaza. However, mapping software needs to be corrected to show the entry/exit ramp as two-way in the direction of  the toll plaza. (It is only one-way exiting from the SB I-95 until it gets to that small access road. 
This causes local people wishing to access the local EV chargers to get incorrect mapping information that directs them several miles north to the next exit before doing a u-turn to return to this point. 
Unlike the NB side, local entry into the plaza is legal and allowed through the SB toll plaza. It’s just that the mapping software need to be updated to make that section of the SB exit ramp roadway two-way.
