June 15, 2014 – (Left) A green reinforcement cage is inserted into a 72-foot-long caisson on the west side of the Dearborn Street Bridge on June 9 in this photo released on Friday by the Chicago Department of Transportation. The cage will make the concrete stronger when it is poured into the caisson.

Two caissons have now been pounded into place under the Clark Street Bridge. The bridge will be closed again this week with both leafs up from Tuesday at 7 a.m. to Friday at 8 p.m.

The bridge was closed last week from Thursday morning to Friday afternoon.

CDOT plans to finish with Clark Street this week. Dearborn Street will be next. The tentative schedule is for it to be closed from Tuesday, June 24, through Monday, June 30. The State Street Bridge will be closed in mid-July.

As they extend the Chicago Riverwalk toward LaSalle, construction crews will continue to back-fill with crushed stone the 25-foot-wide gap between the old and new river walls between State and Dearborn Streets.

(Above) The Clark Street Bridge is raised early Friday morning so that work can be done underneath. (Click on images to view larger versions.)
