Jim Hamre of WMATA pointed out that Metro’s current thinking on the separate Blue Line is that it would have to run one block west of the current Rosslyn station, to a new set of platforms connected by an underground walkway. I had hoped that the new tracks could pass right next to the old ones enabling a cross-platform transfer (after all, Rosslyn already has the two tracks on separate levels), but it appears this is not the case. I’ve updated the Metro 2030 map to reflect this station configuration.
