Construction is progressing on both sides of the Mississippi River. Ongoing Illinois roadway work includes constructing a westbound lane & shoulder in addition to constructing a shoulder associated with the eastbound lanes. River bridge construction over the Illinois flood plain is progressing with the placement of pier caps on several piers of the eastbound structure. Work in the river near the Illinois bank is progressing; however, extremely low river levels are complicating river work near the Missouri bank. Ongoing Missouri roadway work near Riverview Drive and I-270 is expected to include construction of temporary pavement required to keep I-270 open to traffic. A temporary barrier wall will be placed along I-270 near Riverview Drive to protect workers and allow for the removal of guardrail in this vicinity.
