The North Bank Bridge is a bike/pedestrian connection from Cambridge (EF Building/North Point Park) to City Square Charlestown, crossing over the Duck Boat launch ramp, over North Station tracks (just a few feet north of Tower A), over Millers River, and under the Leverett/Zakim bridges.

The building itself does not preclude the tracks. The hospital was hesitant to move it, for fear of cutting off supplying to their patients during the transfer to a new tank.

Today they were erecting two of the biggest mobile cranes I've ever seen... One right next to Tower A and the other South side of the RoW right next to the draw bridge.

You can't really get across the Millers' River, so I'm not sure many people would be crossing the tracks. Nor can you go around the non-culvert portion unless you go through Boston Sand & Gravel.

Arlington wrote:Did you happen to notice how much space is left under it on the west side of the existing tracks? I'm hoping there's room for 1 or 2 additional tracks on the west in a box bounded on the east by the existing tracks, on the west by the "skate park-duck boat" fence and bounded above by the new bridge (and drawbridge clearance).
