Due to high daytime temperatures, the first stage of the bridge deck over the Chicago River must be poured overnight. This work is expected to begin at 9 PM on Thursday, August 4th, and extend to 6 AM Friday, August 5th. In case of rain, Friday night will be used as an alternative to this work.
During this time traffic will be reduced to one lane across the river bridge. Flaggers will be maintaining traffic flow on Western Avenue while this work is taking place.
