Check out this recent post on Syracuse Urban Properties (aka Syrup) about using a trolley or tram to bring visitors from DestiNY USA to downtown. We are in favor of that scenario, and would also recommend reviving OnTrack service through the city.
Anyone who’s ridden Centro’s jam-packed SU-Destiny Route on a Friday evening would agree. OnTrack would certainly be beneficial during any construction or demolition of Route I81.
