Just north of Riverdale Park Station, a wooded tract of land sits for sale. On state property records, its listed at 4535 Albion Road. If you’ve ever driven between College Park and Hyattsville on Baltimore Avenue, you’ll recognize it by the grove of bamboo that fronts the eastern edge of the roadway. It is owned by the Washington Metropolitan Area Transit Authority, which purchased the land for just under $432,000 in 1989 as it prepared to construct Metrorail’s Green Line out to Greenbelt. Underneath, tunnels carry trains between College Park and Prince George’s Plaza Metro stations. WMATA has recently listed the 12-acre property for sale.
