The secret Backup of Shame ramp in the North End for truckers who nearly storrow at the Callahan

Finn witnessed one of the rarest of Boston sights this afternoon: Somebody actually using the normally blocked ramp down from North and Cross streets down to the Callahan Tunnel, across from the old Tunnel Administration building.

In this case, state troopers carefully directed the driver of a pituitary-case 18-wheeler back up from the tunnel ramp to the street, because the way forward would have meant either peeling the entire top of the truck back or getting jammed in at the entrance, which would be nobody's idea of fun.

Although nowhere near as common as storrowings on, well, Storrow Drive, this sort of thing is not unknown at that spot.
