The Greater Greater Washington blog looks at what’s publicly known about a private advocacy group’s proposal to build a parallel, 27-mile-long monorail line in the I-270 corridor north Washington, DC. The blog post notes, Maryland officials “have promised to consider” building the facility in conjunction with plans to widen I-270 by adding tolled express lanes. (Proponents of the monorail project have posted a video overview of their proposal.)
