Town officials are seeking state funds to pursue a long-sought sidewalk installation at Talmadge Hill that’s designed to improve pedestrian safety for rail commuters. The estimated $350,000 project would see a new, five-foot-wide concrete sidewalk and granite curb run along the northern edge of Talmadge Hill Road from Route 106 up to and past the highest parking tier above the heavily used railroad station, according to Public Works Director Tiger Man. It would replace and extend what’s there now, a blacktop sidewalk with a blacktop curb, Mann told members of the Board of Selectmen at their regular meeting Wednesday. “This has been an area that people have asked for for a number of years,” Mann said at the meeting, held in Town Hall. Before and after work, scores of rail commuters make their way to and from the platform at Talmadge Hill, between cars parked in the lots as well as idling cars that pull over on the narrow road to drop them off and pick them up.
