A group of downtown residents and commercial real estate companies have filed suit against Providence and the state, hoping to halt work on the proposed Providence transit center. The suit comes at the plan in a number of ways, hoping that the proposed intermodal center at the Providence rail station and the high-speed bus lane planned to run from the train station to the city’s south side will be re-worked. Among the objectors is former Providence Mayor Joseph R. Paolino Jr., who owns a number of commercial real estate properties along the proposed bus lane. Paolino and other property owners have formed Concerned Citizens of Capital Center LLC, and the group contends that the transit project would adversely affect their property values as well as negatively affect the enjoyment of their holdings. Is their argument valid or is it just a case of NIMBY-ism?
