Greyhound wants to travel a familiar route. Fresh off finding a buyer for the full city block downtown where its bus station used to be, the Dallas-based transportation company now wants to sell its other major land holding in Denver. The site, which Greyhound has controlled since the 1980s, consists of multiple parcels across two adjacent blocks in Five Points: 2450 Curtis St., a 0.93-acre parcel with about 37,000 building square feet on it, according to property records.
