The rails-to-trails line is complete from the southern end of town to Lazy Lane. The State Department of Transportation is ready to finish the trail from there to the Plainville town line, town officials said, but have been held up in talks with Yarde Metals over an easement across company property. Paul Chaplinsky, a Town Council Republican and public works committee vice chairman, said he’s glad that Yarde Metals owners haven’t shut the door to talks altogether. Proposals have gone back and forth between state officials and town engineers and the company. Yarde Metals would retain ownership of the property but allow the trail to be built and maintained.
