Cost of new Bethesda Metro entrance near Purple Line increases by $22.6 million

The estimated cost of building a connection for passengers to transfer between Metro’s Red Line Bethesda station and the future Purple Line stop nearby has grown by $22.6 million, a Montgomery County official said. The additional funding to build a mezzanine at a new Metro station entrance would increase the project’s budget by 20 percent. Montgomery has allotted $110.2 million to build a southern entrance to the underground Bethesda Metro station at Wisconsin Avenue and Elm Street, near the western terminus for the street-level Purple Line
