A recently constructed Bronx motel has been transformed into a new Howard Johnson on a 18,506-square-foot lot at 1300 Sedgwick Ave., also known as 290-1300 Major Deegan Blvd. Seven Hills Hospitality Group LLC bought the property at a cost of $6.41 million, or about $142,444 per room, from the group 1300 Aquino Bronx Corp. The new Howard Johnson will open in one month’s time with some modifications to the original building.
