Though not well publicized, Pond Street in Winchester and Lake Street in Woburn is a no heavy trucking zone. In fact, I know of only one sign (at the corner of Main and Lake Streets in Woburn). But the rule was confirmed by the Winchester Board of Selectmen in response to a question by Bob Cummings at a Selectmen meeting in October(?) 2009.
Yet I often see 18-wheelers and other heavy trucks on Pond Street. I even saw an 18-wheeler with a wide load come down the road the other day. I didn't have my camera with me but plan to post photos of offenders here. If you get a picture of a heavy truck (think big box truck, 18-wheeler, or other really big truck, not contractor's pickups and vans) on Pond Street send it to me and I'll upload the most egregious to this post!
