What is the project?

The Missouri Department of Transportation (MoDOT) is currently designing a new diamond interchange for Riverview Drive at I-270. The interchange is being reconstructed to accommodate the Illinois Department of Transportation's (IDOT) proposed I-270 Chain of Rocks bridge replacement project.

What is expected after construction?

The Riverview Drive interchange will be reconstructed to six lanes of traffic as same as the lanes of traffic proposed in the Chain of Rocks bridge project. The interchange and the new bridge will be striped for four lanes initially, but will be eventually be constructed to six lanes of traffic when I-270, east and west of Riverview Drive, are widened to six traffic lanes.

When will construction begin?

Construction will begin at the end of 2022 and is anticipated to take four years to complete.

What is the cost of this project?

The construction cost is estimated at $24 Million.
