 The old Auburn Railroad followed along the east side of Mill Road, and portions of the trail appear and disappear as modern development encroaches on the original alignment.Yet another stub of the Auburn trail follows south of Thornell Road, just east of Mill Road, in Pittsford, to LaDue Circle and East Street.The trail continues to the southeast of East Street, along the south side of Park Road and continuing to the southeast behind modern housing, crossing Railroad Mills Road at Sturbridge Lane, and continuing to Railroad Mills Road and Woolston Road.
