The Related Group just made one of the priciest land deals of the year, plunking down $57.25 million for 2.8 acres near downtown Miami.

That’s an astonishing $20.45 million per acre for the site at 1400 Biscayne Blvd. across from the Adrienne Arsht Center for the Performing Arts and near the Patricia and Phillip Frost Museum of Science and the Perez Art Museum Miami.
