A dual-level rail and car trench could be located below a slow moving roadway, another one could be below an adjacent woonerf route, and a third could be below buildings adjacent to covered parking.
This narrow trench approach would allow
tree canopies and buildings to span the 24 foot covered trenches while providing two lanes of car traffic below street level.
Reenvisioning Atlanta's East-West CSX Corridor
Initial trench work could focus on the south side of the yard to eliminate Cabbagetown cut-through traffic by providing direct access to below-ground parking. Access to the covered car route could occur within the existing underpasses at Boulevard and Krog Tunnel, thereby preserving these architectural landmarks. The trench height could range from 42 to 55 feet, with the lower 30 feet for freight rail.
The freight rail bridge at the 75/85 freeway could be replaced with a rail tunnel, while raising the current dip in the freeway. Freeway ramps could be added to access the new covered express-route to Decatur. The Decatur Street bridge could be raised and pivoted to align with the new express route while adding a higher crossing at Decatur Street for local traffic, bikes and pedestrians.
