Also at that time, or possibly earlier, the offramp from Route 139 was moved to the right side, and entered the Circle where the connector to Hudson County Boulevard had.
A ramp was built to permit vehicles heading southbound on Tonnele Avenue to access the Pulaski Skyway without entering the circle.
Information on the Tonnele family is sparse, but at least some of them lived in Jersey City, where the street now runs.
There is some confusion about the spelling - whether the name has one 'L' or two - even within Jersey City, and street signs reflect both options.
Postal Service favors "Tonnele," which reflects the spelling of the man after whom the street is named.
