Photos: Backfilling, dewatering, and other fun things to do when building a Riverwalk
15-Apr-16 – Steady, undramatic progress was made this week on the unfinished last three stretches of Chicago Riverwalk. West of Franklin Street, the Riverwalk room known as Boardwalk has been “de-watered” and crews are back-filling with crushed stone. Crews are largely working with concrete, rebar, and wooden forms, though some concrete slabs are in place. Concrete parts of the landscaping are also being installed.

The barge at left contains filters through which water is pumped from areas where it’s not wanted.
