Tehe, I figured out that this road will intersect I-95 based on the signs and the ramp configuration from the pic and went to Google Maps and found a road that matches and then verified with Streetview.
And you're pretty close the correct sign is within a couple miles from where you linked to.
The sign is there because this is the main access road to the airport.
Now I challenge you to find where this is.
uhhhh. I came up with this so far....

BTW if you drive up to Toronto you'll almost certainly past by that area.
