PAMedic-- Check out 00:27 of
this video. I'm not sure if the V-shaped building we see is all the library or if it's the library plus a future building that will be connected. With that in mind, it looks like what you see on the right might be a retaining wall for either that future building / soon-to-be-constructed wing of the JFL.
Rogers3-- I've been wondering about that too. I seem to recall that the contract with Norfolk-Southern specified that both the pedestrian and car tunnels to Wards needed to be completed within a year of each other without LU having to go through an additional approval process, so that would mean that the car tunnels would need to be done in the next 3 or 4 months, if I'm not mistaken.
