Photos show fencing and equipment in preparation for a new residential tower at 234 W Polk Street in South Loop. Known as The Reed, the tower will mark the next stage of a larger megadevelopment called Southbank. While the current prep work for The Reed is taking place further north from where its actual footprint will be, the work is still a critical first step for the development’s construction. Permits posted on-site show that Lendlease is sealing off old freight tunnels that run underneath the Southbank property, thereby allowing for foundation work to proceed on the tower site.
