Not sure what the hangup is with the desire to have the Connector having a NJ Route Number posted, yet never had an issue with the Expressway, Parkway, or Turnpike. Especially the Turnpike, being many people have always thought they were on 95.
At the very least, if the Connector wasn't readily readable to someone calling in for assistance, at least the 'North' and 'South' would give it away on mileposts.
And what may be an unpopular opinion, EMS may be great at saving lives, but many drivers are fairly ditzy when it comes to knowing roads. Even more so when I'll see a cop racing down the shoulder of a highway to get to a crash, then a fire truck racing down the shoulder of the highway...then an Ambulance trying to squeeze between 2 lanes of stopped traffic as they slowly move out of the way...when they could've taken the same shoulder to get to the crash scene.
Even if you trained EMS as to what the route number is, chances are the communication is going to use what is most familiar to those in the field.
That’s why I said “ I believe” in my sentence as margin of error and asking a question of where the first shield really is.
Oh and I stand corrected with mile markers as the Drawbridge has the 64 mile marker from the Delaware Memorial Bridge where I missed it on zooming through GSV.
And a 63.5.
