I-270 North Environmental Assessment

Documents

On April 13, 2017, the Federal Highway Administration issued a Finding of No Significant Impact (FONSI) for this project.  Below is a copy of the final, signed FONSI.

The final public event for the I-270 North EA was held on Thursday, December 15, 2016 at McCluer High School. Attendees were able review the perferred alternative and provide feedback. Below are the handouts that were distributed at the public hearing, as well as the informational boards and video that were displayed.

The Preferred Alternative for upgrading I-270 in North St. Louis County from the I-70 interchange on the west to the Chain of Rocks Bridge on the east is presented below. The alternatives are concepts only. They are not the final plan/designs and are subject to change.

The I-270 North EA chapters are listed below and can be downloaded:

The Preferred Alternative establishes baseline performance measures that must be achieved in the final design. The use of performance measures allows for flexibility and innovation in final design and construction solutions. This flexibility will provide the Missouri Department of Transportation with the ability to accelerate project delivery, improve quality, reduce impacts to the traveling public, and allow for the more efficient use of taxpayer money.
