Hi gdt.  It was a year ago, but it would have likely been the town gis map - from the town's website.  It looks like the street is not on the gis map anymore tho, with only a remnant "North MDW" written were the street used to be.  Maybe it was edited by the town since.  It was edited by someone else on OSM after my edit anyways.  Edit it however you think is appropriate. Thanks.
