RIDGEFIELD—Local business owners and residents said Friday that recent revisions to a renovation plan for Main Street downtown don’t go far enough. The original plan, devised by First Selectman Rudy Marconi in meetings with state transportation officials, would have widened the street, moved the entrance to the CVS parking lot, added a turn lane at Catoonah Street and eliminated some curbside parking spots, all in an effort to smooth downtown traffic.
