The $139 million sale of three Lincoln Road buildings caps a banner year for the popular South Beach retail destination.

With Tuesday’s purchase of buildings at 719, 801 and 826 Lincoln Road by Terranova Corp. and Acadia Realty Trust, the pedestrian mall has had the two most expensive retail transactions of 2012 in South Florida. The buying groups in both sales included institutional investors from New York: Acadia and Vornado Realty Trust, which paid $132 million for 1100 Lincoln Road in July.
