The traffic flow at this point on the entry/exit ramp is two-way. The map currently only shows it as an entry ramp to I-95 NB. However, if I am charging at the Tesla supercharger, I am able to take the parking lot exit onto this entry/exit roadway and turn right to go through the NB exit toll plaza (no charge in this direction exiting) from the highway. The problem is that in my Tesla, the mapping software directs me to the NB route and north several miles up to Biddeford and back to eventually return to where I exit. I think the problem is that the entry/exit ramp needs to be marked as bi-directional exiting from that NB service area parking lot where the EV chargers are located. 

There is a secondary, but related problem. The reverse of this is true in that access into that NB service plaza for charging is not allowed by the service plaza’s rules for entry into it from that same entry/exit ramp. In this case, the employee parking area has signs that prevent cars from entering into the service plaza where EV charging is available. This is not a simple map inaccuracy, but would require the service plaza to change to allow local access without requiring vehicles to drive several miles up the highway and back.
