Introduction The Maryland Transit Administration (MTA) is undertaking an Alternatives Analysis and Draft Environmental Impact Statement (AA/DEIS) to study means for addressing mobility and accessibility issues in the corridor between Bethesda and New Carrollton, in Montgomery and Prince George’s Counties, Maryland, just north of the District of Columbia boundary. The study is considering a range of alternatives to improve east-west transit mobility in the 16-mile corridor that connects
