Freshly mixed concrete is pumped from a Mack truck parked on Wacker Drive through a 131-foot hose snaked around the east side of a Dearborn Street bridge house on June 28. It is filling a 72-foot-long, six-foot-diameter caisson – pounded into the riverbed the previous week – with about 2,000 cubic feet of concrete. Manning the pump is Original Concrete Pumping Service, Inc., of Bensenville, Illinois. (Click on images to view larger versions.)

Riverwalk foundation work returning to Clark Street

By Steven Dahlman

3-Jul-14 – The Clark Street Bridge will be closed for two days next week so that work can be completed on the Riverwalk foundation below the bridge.

The bridge was closed over two weeks in June. It will close again on Monday, July 7 at 7 a.m. and re-open sometime on Wednesday, July 9.

72-foot-long caissons are being pounded into the riverbed underneath the bridges at Clark, Dearborn, and State Streets. The caissons are then filled with concrete. They will anchor the Riverwalk to bedrock below the Chicago River.

As announced last month, the State Street Bridge will be closed for seven days in mid-July but dates and times have not yet been released.

Workers will get Friday, July 4 off but could be back on Saturday, thanks to Monday night’s heavy rains. Although the Chicago Department of Transportation says there was no significant damage, flooding along the Riverwalk did interrupt work and, says CDOT, they may have to make up for some lost time.

That's not a Texas boom that's a Chicago boom

Lol no no. It is called a texas boom when you use system and a crane to make the boom longer. It is a old school way of doing things. Not recommend.

It appears they are using an excavator not a crane, so maybe it is a Chicago boom

lol you might be right.
