DESIGN:
The design stems from earlier wagon wheel designs, in this case in what would have been a 12 spoke wheel, the two horizontal spokes are supplanted by two thinner off-center bars forming in effect a transparent badge.
UTILITY:
In both its design and in its placement this design was frequently associated with drains and sewers, especially in City sponsored projects such as parks, housing or in this case the entrace ramp to the Harlem River Drive.
RANGE:
This design can be spotted throughout the city, with inscribed dates ranging from 1949 to 1998, and with seemingly newer variants still being installed.* This cover is on the Harlem River Driveway down from 155th St in Manhattan.
